Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485884, here are decompositions:

  • 7 + 2147485877 = 2147485884
  • 13 + 2147485871 = 2147485884
  • 17 + 2147485867 = 2147485884
  • 23 + 2147485861 = 2147485884
  • 41 + 2147485843 = 2147485884
  • 43 + 2147485841 = 2147485884
  • 67 + 2147485817 = 2147485884
  • 197 + 2147485687 = 2147485884

Showing the first eight; more decompositions exist.
