Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39490, here are decompositions:

  • 29 + 39461 = 39490
  • 47 + 39443 = 39490
  • 71 + 39419 = 39490
  • 107 + 39383 = 39490
  • 131 + 39359 = 39490
  • 149 + 39341 = 39490
  • 167 + 39323 = 39490
  • 173 + 39317 = 39490

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39490 first appears in π at position 122,273 of the decimal expansion (the 122,273ordinal-suffix:rd 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.
