Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755778, here are decompositions:

  • 37 + 8755741 = 8755778
  • 67 + 8755711 = 8755778
  • 79 + 8755699 = 8755778
  • 139 + 8755639 = 8755778
  • 277 + 8755501 = 8755778
  • 379 + 8755399 = 8755778
  • 397 + 8755381 = 8755778
  • 439 + 8755339 = 8755778

Showing the first eight; more decompositions exist.
