Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468894, here are decompositions:

  • 7 + 2147468887 = 2147468894
  • 13 + 2147468881 = 2147468894
  • 61 + 2147468833 = 2147468894
  • 331 + 2147468563 = 2147468894
  • 397 + 2147468497 = 2147468894
  • 463 + 2147468431 = 2147468894
  • 577 + 2147468317 = 2147468894
  • 661 + 2147468233 = 2147468894

Showing the first eight; more decompositions exist.
