Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468864, here are decompositions:

  • 3 + 2147468861 = 2147468864
  • 31 + 2147468833 = 2147468864
  • 61 + 2147468803 = 2147468864
  • 367 + 2147468497 = 2147468864
  • 421 + 2147468443 = 2147468864
  • 433 + 2147468431 = 2147468864
  • 523 + 2147468341 = 2147468864
  • 547 + 2147468317 = 2147468864

Showing the first eight; more decompositions exist.
