Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501908, here are decompositions:

  • 131 + 2147501777 = 2147501908
  • 191 + 2147501717 = 2147501908
  • 239 + 2147501669 = 2147501908
  • 281 + 2147501627 = 2147501908
  • 389 + 2147501519 = 2147501908
  • 659 + 2147501249 = 2147501908
  • 971 + 2147500937 = 2147501908
  • 977 + 2147500931 = 2147501908

Showing the first eight; more decompositions exist.
