Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45242, here are decompositions:

  • 61 + 45181 = 45242
  • 103 + 45139 = 45242
  • 181 + 45061 = 45242
  • 229 + 45013 = 45242
  • 271 + 44971 = 45242
  • 283 + 44959 = 45242
  • 349 + 44893 = 45242
  • 433 + 44809 = 45242

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45242 first appears in π at position 150,650 of the decimal expansion (the 150,650ordinal-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.
