Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37780, here are decompositions:

  • 89 + 37691 = 37780
  • 131 + 37649 = 37780
  • 137 + 37643 = 37780
  • 173 + 37607 = 37780
  • 191 + 37589 = 37780
  • 233 + 37547 = 37780
  • 251 + 37529 = 37780
  • 263 + 37517 = 37780

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37780 first appears in π at position 188,620 of the decimal expansion (the 188,620ordinal-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.
