Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38898, here are decompositions:

  • 7 + 38891 = 38898
  • 31 + 38867 = 38898
  • 37 + 38861 = 38898
  • 47 + 38851 = 38898
  • 59 + 38839 = 38898
  • 107 + 38791 = 38898
  • 131 + 38767 = 38898
  • 149 + 38749 = 38898

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38898 first appears in π at position 187,268 of the decimal expansion (the 187,268ordinal-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.
