Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491274, here are decompositions:

  • 13 + 491261 = 491274
  • 23 + 491251 = 491274
  • 61 + 491213 = 491274
  • 73 + 491201 = 491274
  • 103 + 491171 = 491274
  • 107 + 491167 = 491274
  • 137 + 491137 = 491274
  • 191 + 491083 = 491274

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 491,274 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 491274 first appears in π at position 572,037 of the decimal expansion (the 572,037ordinal-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.
