Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485942, here are decompositions:

  • 3 + 2147485939 = 2147485942
  • 29 + 2147485913 = 2147485942
  • 53 + 2147485889 = 2147485942
  • 71 + 2147485871 = 2147485942
  • 83 + 2147485859 = 2147485942
  • 101 + 2147485841 = 2147485942
  • 113 + 2147485829 = 2147485942
  • 269 + 2147485673 = 2147485942

Showing the first eight; more decompositions exist.
