Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470142, here are decompositions:

  • 3 + 2147470139 = 2147470142
  • 19 + 2147470123 = 2147470142
  • 31 + 2147470111 = 2147470142
  • 61 + 2147470081 = 2147470142
  • 193 + 2147469949 = 2147470142
  • 199 + 2147469943 = 2147470142
  • 313 + 2147469829 = 2147470142
  • 439 + 2147469703 = 2147470142

Showing the first eight; more decompositions exist.
