Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20118, here are decompositions:

  • 5 + 20113 = 20118
  • 11 + 20107 = 20118
  • 17 + 20101 = 20118
  • 29 + 20089 = 20118
  • 47 + 20071 = 20118
  • 67 + 20051 = 20118
  • 71 + 20047 = 20118
  • 89 + 20029 = 20118

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20118 first appears in π at position 7,719 of the decimal expansion (the 7,719ordinal-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.
