Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126238, here are decompositions:

  • 5 + 126233 = 126238
  • 11 + 126227 = 126238
  • 107 + 126131 = 126238
  • 131 + 126107 = 126238
  • 191 + 126047 = 126238
  • 197 + 126041 = 126238
  • 227 + 126011 = 126238
  • 311 + 125927 = 126238

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 126,238 and was likely granted around 1872.

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

Position in π

The digit sequence 126238 first appears in π at position 550,457 of the decimal expansion (the 550,457ordinal-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.
