Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39938, here are decompositions:

  • 37 + 39901 = 39938
  • 61 + 39877 = 39938
  • 97 + 39841 = 39938
  • 109 + 39829 = 39938
  • 139 + 39799 = 39938
  • 211 + 39727 = 39938
  • 229 + 39709 = 39938
  • 271 + 39667 = 39938

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39938 first appears in π at position 388,718 of the decimal expansion (the 388,718ordinal-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.
