Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987640, here are decompositions:

  • 19 + 4294987621 = 4294987640
  • 61 + 4294987579 = 4294987640
  • 79 + 4294987561 = 4294987640
  • 283 + 4294987357 = 4294987640
  • 337 + 4294987303 = 4294987640
  • 409 + 4294987231 = 4294987640
  • 499 + 4294987141 = 4294987640
  • 673 + 4294986967 = 4294987640

Showing the first eight; more decompositions exist.
