Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38910, here are decompositions:

  • 7 + 38903 = 38910
  • 19 + 38891 = 38910
  • 37 + 38873 = 38910
  • 43 + 38867 = 38910
  • 59 + 38851 = 38910
  • 71 + 38839 = 38910
  • 89 + 38821 = 38910
  • 107 + 38803 = 38910

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38910 first appears in π at position 113,434 of the decimal expansion (the 113,434ordinal-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.
