Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485178, here are decompositions:

  • 37 + 2147485141 = 2147485178
  • 229 + 2147484949 = 2147485178
  • 457 + 2147484721 = 2147485178
  • 499 + 2147484679 = 2147485178
  • 577 + 2147484601 = 2147485178
  • 661 + 2147484517 = 2147485178
  • 739 + 2147484439 = 2147485178
  • 829 + 2147484349 = 2147485178

Showing the first eight; more decompositions exist.
