Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71378, here are decompositions:

  • 19 + 71359 = 71378
  • 31 + 71347 = 71378
  • 37 + 71341 = 71378
  • 61 + 71317 = 71378
  • 211 + 71167 = 71378
  • 367 + 71011 = 71378
  • 379 + 70999 = 71378
  • 397 + 70981 = 71378

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71378 first appears in π at position 1,927 of the decimal expansion (the 1,927ordinal-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.
