Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469968, here are decompositions:

  • 19 + 2147469949 = 2147469968
  • 139 + 2147469829 = 2147469968
  • 151 + 2147469817 = 2147469968
  • 331 + 2147469637 = 2147469968
  • 349 + 2147469619 = 2147469968
  • 547 + 2147469421 = 2147469968
  • 739 + 2147469229 = 2147469968
  • 811 + 2147469157 = 2147469968

Showing the first eight; more decompositions exist.
