Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27198, here are decompositions:

  • 7 + 27191 = 27198
  • 19 + 27179 = 27198
  • 71 + 27127 = 27198
  • 89 + 27109 = 27198
  • 107 + 27091 = 27198
  • 131 + 27067 = 27198
  • 137 + 27061 = 27198
  • 139 + 27059 = 27198

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27198 first appears in π at position 13,093 of the decimal expansion (the 13,093ordinal-suffix:rd 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.
