Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38500, here are decompositions:

  • 41 + 38459 = 38500
  • 47 + 38453 = 38500
  • 53 + 38447 = 38500
  • 107 + 38393 = 38500
  • 149 + 38351 = 38500
  • 167 + 38333 = 38500
  • 173 + 38327 = 38500
  • 179 + 38321 = 38500

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38500 first appears in π at position 141,939 of the decimal expansion (the 141,939ordinal-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.
