Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77138, here are decompositions:

  • 37 + 77101 = 77138
  • 97 + 77041 = 77138
  • 109 + 77029 = 77138
  • 307 + 76831 = 77138
  • 337 + 76801 = 77138
  • 367 + 76771 = 77138
  • 421 + 76717 = 77138
  • 487 + 76651 = 77138

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77138 first appears in π at position 212,164 of the decimal expansion (the 212,164ordinal-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.
