Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399086, here are decompositions:

  • 17 + 2147399069 = 2147399086
  • 23 + 2147399063 = 2147399086
  • 89 + 2147398997 = 2147399086
  • 137 + 2147398949 = 2147399086
  • 167 + 2147398919 = 2147399086
  • 317 + 2147398769 = 2147399086
  • 419 + 2147398667 = 2147399086
  • 509 + 2147398577 = 2147399086

Showing the first eight; more decompositions exist.
