Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37520, here are decompositions:

  • 3 + 37517 = 37520
  • 13 + 37507 = 37520
  • 19 + 37501 = 37520
  • 31 + 37489 = 37520
  • 37 + 37483 = 37520
  • 73 + 37447 = 37520
  • 79 + 37441 = 37520
  • 97 + 37423 = 37520

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37520 first appears in π at position 164,608 of the decimal expansion (the 164,608ordinal-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.
