Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38998, here are decompositions:

  • 5 + 38993 = 38998
  • 107 + 38891 = 38998
  • 131 + 38867 = 38998
  • 137 + 38861 = 38998
  • 251 + 38747 = 38998
  • 269 + 38729 = 38998
  • 347 + 38651 = 38998
  • 359 + 38639 = 38998

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38998 first appears in π at position 56,140 of the decimal expansion (the 56,140ordinal-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.
