Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945878, here are decompositions:

  • 61 + 945817 = 945878
  • 67 + 945811 = 945878
  • 79 + 945799 = 945878
  • 139 + 945739 = 945878
  • 277 + 945601 = 945878
  • 331 + 945547 = 945878
  • 397 + 945481 = 945878
  • 421 + 945457 = 945878

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 945,878 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 945878 first appears in π at position 148,753 of the decimal expansion (the 148,753ordinal-suffix:rd 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.
