Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41578, here are decompositions:

  • 29 + 41549 = 41578
  • 59 + 41519 = 41578
  • 71 + 41507 = 41578
  • 167 + 41411 = 41578
  • 179 + 41399 = 41578
  • 191 + 41387 = 41578
  • 197 + 41381 = 41578
  • 227 + 41351 = 41578

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 41578 first appears in π at position 79,360 of the decimal expansion (the 79,360ordinal-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.
