Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489040, here are decompositions:

  • 29 + 489011 = 489040
  • 47 + 488993 = 489040
  • 59 + 488981 = 489040
  • 131 + 488909 = 489040
  • 179 + 488861 = 489040
  • 281 + 488759 = 489040
  • 311 + 488729 = 489040
  • 317 + 488723 = 489040

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 489,040 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 489040 first appears in π at position 619,626 of the decimal expansion (the 619,626ordinal-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.
