Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90918, here are decompositions:

  • 7 + 90911 = 90918
  • 11 + 90907 = 90918
  • 17 + 90901 = 90918
  • 31 + 90887 = 90918
  • 71 + 90847 = 90918
  • 97 + 90821 = 90918
  • 131 + 90787 = 90918
  • 239 + 90679 = 90918

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 90918 first appears in π at position 34,566 of the decimal expansion (the 34,566ordinal-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.
