Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490976, here are decompositions:

  • 3 + 2147490973 = 2147490976
  • 23 + 2147490953 = 2147490976
  • 53 + 2147490923 = 2147490976
  • 179 + 2147490797 = 2147490976
  • 317 + 2147490659 = 2147490976
  • 383 + 2147490593 = 2147490976
  • 419 + 2147490557 = 2147490976
  • 563 + 2147490413 = 2147490976

Showing the first eight; more decompositions exist.
