Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469678, here are decompositions:

  • 19 + 2147469659 = 2147469678
  • 41 + 2147469637 = 2147469678
  • 59 + 2147469619 = 2147469678
  • 157 + 2147469521 = 2147469678
  • 229 + 2147469449 = 2147469678
  • 257 + 2147469421 = 2147469678
  • 331 + 2147469347 = 2147469678
  • 349 + 2147469329 = 2147469678

Showing the first eight; more decompositions exist.
