Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655472, here are decompositions:

  • 71 + 8655401 = 8655472
  • 101 + 8655371 = 8655472
  • 401 + 8655071 = 8655472
  • 431 + 8655041 = 8655472
  • 443 + 8655029 = 8655472
  • 461 + 8655011 = 8655472
  • 491 + 8654981 = 8655472
  • 599 + 8654873 = 8655472

Showing the first eight; more decompositions exist.
