Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42736, here are decompositions:

  • 17 + 42719 = 42736
  • 47 + 42689 = 42736
  • 53 + 42683 = 42736
  • 59 + 42677 = 42736
  • 167 + 42569 = 42736
  • 179 + 42557 = 42736
  • 227 + 42509 = 42736
  • 263 + 42473 = 42736

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42736 first appears in π at position 30,906 of the decimal expansion (the 30,906ordinal-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.
