Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375008, here are decompositions:

  • 11 + 2147374997 = 2147375008
  • 167 + 2147374841 = 2147375008
  • 281 + 2147374727 = 2147375008
  • 431 + 2147374577 = 2147375008
  • 677 + 2147374331 = 2147375008
  • 839 + 2147374169 = 2147375008
  • 881 + 2147374127 = 2147375008
  • 887 + 2147374121 = 2147375008

Showing the first eight; more decompositions exist.
