Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1192, here are decompositions:

  • 5 + 1187 = 1192
  • 11 + 1181 = 1192
  • 29 + 1163 = 1192
  • 41 + 1151 = 1192
  • 83 + 1109 = 1192
  • 89 + 1103 = 1192
  • 101 + 1091 = 1192
  • 131 + 1061 = 1192

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1192 first appears in π at position 16,528 of the decimal expansion (the 16,528ordinal-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.
