Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638804, here are decompositions:

  • 71 + 8638733 = 8638804
  • 107 + 8638697 = 8638804
  • 113 + 8638691 = 8638804
  • 347 + 8638457 = 8638804
  • 353 + 8638451 = 8638804
  • 401 + 8638403 = 8638804
  • 431 + 8638373 = 8638804
  • 467 + 8638337 = 8638804

Showing the first eight; more decompositions exist.
