Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38538, here are decompositions:

  • 37 + 38501 = 38538
  • 79 + 38459 = 38538
  • 89 + 38449 = 38538
  • 107 + 38431 = 38538
  • 167 + 38371 = 38538
  • 211 + 38327 = 38538
  • 239 + 38299 = 38538
  • 251 + 38287 = 38538

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38538 first appears in π at position 699,936 of the decimal expansion (the 699,936ordinal-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.
