Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470190, here are decompositions:

  • 7 + 2147470183 = 2147470190
  • 13 + 2147470177 = 2147470190
  • 43 + 2147470147 = 2147470190
  • 67 + 2147470123 = 2147470190
  • 79 + 2147470111 = 2147470190
  • 109 + 2147470081 = 2147470190
  • 163 + 2147470027 = 2147470190
  • 241 + 2147469949 = 2147470190

Showing the first eight; more decompositions exist.
