Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399210, here are decompositions:

  • 7 + 2147399203 = 2147399210
  • 13 + 2147399197 = 2147399210
  • 43 + 2147399167 = 2147399210
  • 97 + 2147399113 = 2147399210
  • 157 + 2147399053 = 2147399210
  • 193 + 2147399017 = 2147399210
  • 241 + 2147398969 = 2147399210
  • 613 + 2147398597 = 2147399210

Showing the first eight; more decompositions exist.
