Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470238, here are decompositions:

  • 61 + 2147470177 = 2147470238
  • 127 + 2147470111 = 2147470238
  • 157 + 2147470081 = 2147470238
  • 181 + 2147470057 = 2147470238
  • 211 + 2147470027 = 2147470238
  • 409 + 2147469829 = 2147470238
  • 421 + 2147469817 = 2147470238
  • 457 + 2147469781 = 2147470238

Showing the first eight; more decompositions exist.
