Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10118, here are decompositions:

  • 7 + 10111 = 10118
  • 19 + 10099 = 10118
  • 79 + 10039 = 10118
  • 109 + 10009 = 10118
  • 151 + 9967 = 10118
  • 211 + 9907 = 10118
  • 307 + 9811 = 10118
  • 331 + 9787 = 10118

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10118 first appears in π at position 49,749 of the decimal expansion (the 49,749ordinal-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.
