Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491524, here are decompositions:

  • 23 + 491501 = 491524
  • 41 + 491483 = 491524
  • 101 + 491423 = 491524
  • 107 + 491417 = 491524
  • 167 + 491357 = 491524
  • 191 + 491333 = 491524
  • 197 + 491327 = 491524
  • 227 + 491297 = 491524

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 491,524 and was likely granted around 1893.

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

Position in π

The digit sequence 491524 first appears in π at position 94,504 of the decimal expansion (the 94,504ordinal-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.
