Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468902, here are decompositions:

  • 41 + 2147468861 = 2147468902
  • 101 + 2147468801 = 2147468902
  • 149 + 2147468753 = 2147468902
  • 251 + 2147468651 = 2147468902
  • 263 + 2147468639 = 2147468902
  • 281 + 2147468621 = 2147468902
  • 311 + 2147468591 = 2147468902
  • 479 + 2147468423 = 2147468902

Showing the first eight; more decompositions exist.
