Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38578, here are decompositions:

  • 11 + 38567 = 38578
  • 17 + 38561 = 38578
  • 131 + 38447 = 38578
  • 227 + 38351 = 38578
  • 251 + 38327 = 38578
  • 257 + 38321 = 38578
  • 317 + 38261 = 38578
  • 347 + 38231 = 38578

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38578 first appears in π at position 8,135 of the decimal expansion (the 8,135ordinal-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.
