Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123658, here are decompositions:

  • 5 + 123653 = 123658
  • 107 + 123551 = 123658
  • 131 + 123527 = 123658
  • 167 + 123491 = 123658
  • 179 + 123479 = 123658
  • 239 + 123419 = 123658
  • 251 + 123407 = 123658
  • 257 + 123401 = 123658

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 123,658 and was likely granted around 1871.

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

Position in π

The digit sequence 123658 first appears in π at position 305,577 of the decimal expansion (the 305,577ordinal-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.
