Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469874, here are decompositions:

  • 281 + 2147469593 = 2147469874
  • 353 + 2147469521 = 2147469874
  • 383 + 2147469491 = 2147469874
  • 701 + 2147469173 = 2147469874
  • 743 + 2147469131 = 2147469874
  • 761 + 2147469113 = 2147469874
  • 773 + 2147469101 = 2147469874
  • 827 + 2147469047 = 2147469874

Showing the first eight; more decompositions exist.
