Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489660, here are decompositions:

  • 7 + 489653 = 489660
  • 29 + 489631 = 489660
  • 47 + 489613 = 489660
  • 89 + 489571 = 489660
  • 103 + 489557 = 489660
  • 107 + 489553 = 489660
  • 109 + 489551 = 489660
  • 131 + 489529 = 489660

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 489,660 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 489660 first appears in π at position 380,417 of the decimal expansion (the 380,417ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
