Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12850, here are decompositions:

  • 29 + 12821 = 12850
  • 41 + 12809 = 12850
  • 59 + 12791 = 12850
  • 107 + 12743 = 12850
  • 137 + 12713 = 12850
  • 179 + 12671 = 12850
  • 191 + 12659 = 12850
  • 197 + 12653 = 12850

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12850 first appears in π at position 429,044 of the decimal expansion (the 429,044ordinal-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.
