Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10138, here are decompositions:

  • 5 + 10133 = 10138
  • 47 + 10091 = 10138
  • 59 + 10079 = 10138
  • 71 + 10067 = 10138
  • 101 + 10037 = 10138
  • 131 + 10007 = 10138
  • 197 + 9941 = 10138
  • 251 + 9887 = 10138

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10138 first appears in π at position 64,665 of the decimal expansion (the 64,665ordinal-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.
