Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491264, here are decompositions:

  • 3 + 491261 = 491264
  • 13 + 491251 = 491264
  • 97 + 491167 = 491264
  • 127 + 491137 = 491264
  • 181 + 491083 = 491264
  • 223 + 491041 = 491264
  • 271 + 490993 = 491264
  • 307 + 490957 = 491264

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 491,264 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 491264 first appears in π at position 92,710 of the decimal expansion (the 92,710ordinal-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.
