Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81062, here are decompositions:

  • 13 + 81049 = 81062
  • 19 + 81043 = 81062
  • 31 + 81031 = 81062
  • 43 + 81019 = 81062
  • 61 + 81001 = 81062
  • 73 + 80989 = 81062
  • 109 + 80953 = 81062
  • 139 + 80923 = 81062

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 81062 first appears in π at position 19,954 of the decimal expansion (the 19,954ordinal-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.
