Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478868, here are decompositions:

  • 7 + 478861 = 478868
  • 37 + 478831 = 478868
  • 67 + 478801 = 478868
  • 127 + 478741 = 478868
  • 139 + 478729 = 478868
  • 157 + 478711 = 478868
  • 241 + 478627 = 478868
  • 337 + 478531 = 478868

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 478,868 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 478868 first appears in π at position 58,964 of the decimal expansion (the 58,964ordinal-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.
