Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42726, here are decompositions:

  • 7 + 42719 = 42726
  • 17 + 42709 = 42726
  • 23 + 42703 = 42726
  • 29 + 42697 = 42726
  • 37 + 42689 = 42726
  • 43 + 42683 = 42726
  • 59 + 42667 = 42726
  • 83 + 42643 = 42726

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42726 first appears in π at position 14,415 of the decimal expansion (the 14,415ordinal-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.
