Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491308, here are decompositions:

  • 11 + 491297 = 491308
  • 29 + 491279 = 491308
  • 47 + 491261 = 491308
  • 89 + 491219 = 491308
  • 107 + 491201 = 491308
  • 137 + 491171 = 491308
  • 149 + 491159 = 491308
  • 179 + 491129 = 491308

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 491,308 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 491308 first appears in π at position 478,379 of the decimal expansion (the 478,379ordinal-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.
