Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625778, here are decompositions:

  • 71 + 8625707 = 8625778
  • 89 + 8625689 = 8625778
  • 137 + 8625641 = 8625778
  • 179 + 8625599 = 8625778
  • 191 + 8625587 = 8625778
  • 251 + 8625527 = 8625778
  • 257 + 8625521 = 8625778
  • 269 + 8625509 = 8625778

Showing the first eight; more decompositions exist.
