Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425864, here are decompositions:

  • 11 + 2147425853 = 2147425864
  • 257 + 2147425607 = 2147425864
  • 677 + 2147425187 = 2147425864
  • 743 + 2147425121 = 2147425864
  • 761 + 2147425103 = 2147425864
  • 797 + 2147425067 = 2147425864
  • 863 + 2147425001 = 2147425864
  • 971 + 2147424893 = 2147425864

Showing the first eight; more decompositions exist.
