Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124724, here are decompositions:

  • 3 + 124721 = 124724
  • 7 + 124717 = 124724
  • 31 + 124693 = 124724
  • 157 + 124567 = 124724
  • 163 + 124561 = 124724
  • 181 + 124543 = 124724
  • 211 + 124513 = 124724
  • 277 + 124447 = 124724

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 124,724 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 124724 first appears in π at position 316,460 of the decimal expansion (the 316,460ordinal-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.
