Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1182, here are decompositions:

  • 11 + 1171 = 1182
  • 19 + 1163 = 1182
  • 29 + 1153 = 1182
  • 31 + 1151 = 1182
  • 53 + 1129 = 1182
  • 59 + 1123 = 1182
  • 73 + 1109 = 1182
  • 79 + 1103 = 1182

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1182 first appears in π at position 14,376 of the decimal expansion (the 14,376ordinal-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.
