Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38530, here are decompositions:

  • 29 + 38501 = 38530
  • 71 + 38459 = 38530
  • 83 + 38447 = 38530
  • 137 + 38393 = 38530
  • 179 + 38351 = 38530
  • 197 + 38333 = 38530
  • 227 + 38303 = 38530
  • 257 + 38273 = 38530

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38530 first appears in π at position 4,714 of the decimal expansion (the 4,714ordinal-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.
