Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8198, here are decompositions:

  • 7 + 8191 = 8198
  • 19 + 8179 = 8198
  • 31 + 8167 = 8198
  • 37 + 8161 = 8198
  • 97 + 8101 = 8198
  • 109 + 8089 = 8198
  • 139 + 8059 = 8198
  • 181 + 8017 = 8198

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8198 first appears in π at position 7,040 of the decimal expansion (the 7,040ordinal-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.
