Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467240, here are decompositions:

  • 29 + 2147467211 = 2147467240
  • 71 + 2147467169 = 2147467240
  • 173 + 2147467067 = 2147467240
  • 197 + 2147467043 = 2147467240
  • 293 + 2147466947 = 2147467240
  • 557 + 2147466683 = 2147467240
  • 599 + 2147466641 = 2147467240
  • 701 + 2147466539 = 2147467240

Showing the first eight; more decompositions exist.
