Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487930, here are decompositions:

  • 41 + 487889 = 487930
  • 101 + 487829 = 487930
  • 137 + 487793 = 487930
  • 173 + 487757 = 487930
  • 197 + 487733 = 487930
  • 227 + 487703 = 487930
  • 239 + 487691 = 487930
  • 281 + 487649 = 487930

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 487,930 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 487930 first appears in π at position 16,698 of the decimal expansion (the 16,698ordinal-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.
