Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491270, here are decompositions:

  • 19 + 491251 = 491270
  • 103 + 491167 = 491270
  • 211 + 491059 = 491270
  • 229 + 491041 = 491270
  • 277 + 490993 = 491270
  • 313 + 490957 = 491270
  • 349 + 490921 = 491270
  • 379 + 490891 = 491270

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 491,270 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 491270 first appears in π at position 129,995 of the decimal expansion (the 129,995ordinal-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.
