Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45538, here are decompositions:

  • 5 + 45533 = 45538
  • 41 + 45497 = 45538
  • 47 + 45491 = 45538
  • 149 + 45389 = 45538
  • 197 + 45341 = 45538
  • 257 + 45281 = 45538
  • 347 + 45191 = 45538
  • 359 + 45179 = 45538

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45538 first appears in π at position 6,761 of the decimal expansion (the 6,761ordinal-suffix:st 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.
