Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38828, here are decompositions:

  • 7 + 38821 = 38828
  • 37 + 38791 = 38828
  • 61 + 38767 = 38828
  • 79 + 38749 = 38828
  • 151 + 38677 = 38828
  • 157 + 38671 = 38828
  • 199 + 38629 = 38828
  • 271 + 38557 = 38828

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38828 first appears in π at position 86,507 of the decimal expansion (the 86,507ordinal-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.
