Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1262, here are decompositions:

  • 3 + 1259 = 1262
  • 13 + 1249 = 1262
  • 31 + 1231 = 1262
  • 61 + 1201 = 1262
  • 109 + 1153 = 1262
  • 139 + 1123 = 1262
  • 193 + 1069 = 1262
  • 199 + 1063 = 1262

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1262 first appears in π at position 4,372 of the decimal expansion (the 4,372ordinal-suffix:nd 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.
