Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38806, here are decompositions:

  • 3 + 38803 = 38806
  • 23 + 38783 = 38806
  • 59 + 38747 = 38806
  • 83 + 38723 = 38806
  • 107 + 38699 = 38806
  • 113 + 38693 = 38806
  • 137 + 38669 = 38806
  • 167 + 38639 = 38806

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38806 first appears in π at position 96,774 of the decimal expansion (the 96,774ordinal-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.
