Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124658, here are decompositions:

  • 97 + 124561 = 124658
  • 181 + 124477 = 124658
  • 199 + 124459 = 124658
  • 211 + 124447 = 124658
  • 229 + 124429 = 124658
  • 307 + 124351 = 124658
  • 349 + 124309 = 124658
  • 367 + 124291 = 124658

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 124,658 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 124658 first appears in π at position 470,123 of the decimal expansion (the 470,123ordinal-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.
