Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43580, here are decompositions:

  • 3 + 43577 = 43580
  • 7 + 43573 = 43580
  • 37 + 43543 = 43580
  • 139 + 43441 = 43580
  • 181 + 43399 = 43580
  • 373 + 43207 = 43580
  • 379 + 43201 = 43580
  • 421 + 43159 = 43580

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43580 first appears in π at position 39,635 of the decimal expansion (the 39,635ordinal-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.
