Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422988, here are decompositions:

  • 97 + 2147422891 = 2147422988
  • 127 + 2147422861 = 2147422988
  • 199 + 2147422789 = 2147422988
  • 211 + 2147422777 = 2147422988
  • 241 + 2147422747 = 2147422988
  • 331 + 2147422657 = 2147422988
  • 439 + 2147422549 = 2147422988
  • 499 + 2147422489 = 2147422988

Showing the first eight; more decompositions exist.
