Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587660, here are decompositions:

  • 41 + 2147587619 = 2147587660
  • 137 + 2147587523 = 2147587660
  • 233 + 2147587427 = 2147587660
  • 263 + 2147587397 = 2147587660
  • 353 + 2147587307 = 2147587660
  • 419 + 2147587241 = 2147587660
  • 431 + 2147587229 = 2147587660
  • 599 + 2147587061 = 2147587660

Showing the first eight; more decompositions exist.
