Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147563238, here are decompositions:

  • 31 + 2147563207 = 2147563238
  • 61 + 2147563177 = 2147563238
  • 151 + 2147563087 = 2147563238
  • 307 + 2147562931 = 2147563238
  • 397 + 2147562841 = 2147563238
  • 409 + 2147562829 = 2147563238
  • 727 + 2147562511 = 2147563238
  • 829 + 2147562409 = 2147563238

Showing the first eight; more decompositions exist.
