Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77908, here are decompositions:

  • 41 + 77867 = 77908
  • 59 + 77849 = 77908
  • 107 + 77801 = 77908
  • 197 + 77711 = 77908
  • 227 + 77681 = 77908
  • 317 + 77591 = 77908
  • 359 + 77549 = 77908
  • 419 + 77489 = 77908

Showing the first eight; more decompositions exist.
