Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489722, here are decompositions:

  • 31 + 489691 = 489722
  • 43 + 489679 = 489722
  • 109 + 489613 = 489722
  • 151 + 489571 = 489722
  • 193 + 489529 = 489722
  • 229 + 489493 = 489722
  • 283 + 489439 = 489722
  • 313 + 489409 = 489722

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 489,722 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 489722 first appears in π at position 196,200 of the decimal expansion (the 196,200ordinal-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.
