Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758778, here are decompositions:

  • 31 + 8758747 = 8758778
  • 109 + 8758669 = 8758778
  • 181 + 8758597 = 8758778
  • 229 + 8758549 = 8758778
  • 241 + 8758537 = 8758778
  • 271 + 8758507 = 8758778
  • 277 + 8758501 = 8758778
  • 331 + 8758447 = 8758778

Showing the first eight; more decompositions exist.
