Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147578726, here are decompositions:

  • 89 + 2147578637 = 2147578726
  • 107 + 2147578619 = 2147578726
  • 113 + 2147578613 = 2147578726
  • 173 + 2147578553 = 2147578726
  • 197 + 2147578529 = 2147578726
  • 239 + 2147578487 = 2147578726
  • 257 + 2147578469 = 2147578726
  • 263 + 2147578463 = 2147578726

Showing the first eight; more decompositions exist.
