Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619520, here are decompositions:

  • 11 + 8619509 = 8619520
  • 29 + 8619491 = 8619520
  • 47 + 8619473 = 8619520
  • 59 + 8619461 = 8619520
  • 83 + 8619437 = 8619520
  • 89 + 8619431 = 8619520
  • 167 + 8619353 = 8619520
  • 251 + 8619269 = 8619520

Showing the first eight; more decompositions exist.
