Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491272, here are decompositions:

  • 11 + 491261 = 491272
  • 53 + 491219 = 491272
  • 59 + 491213 = 491272
  • 71 + 491201 = 491272
  • 101 + 491171 = 491272
  • 113 + 491159 = 491272
  • 191 + 491081 = 491272
  • 233 + 491039 = 491272

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 491,272 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 491272 first appears in π at position 207,361 of the decimal expansion (the 207,361ordinal-suffix:st 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.
