Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147525818, here are decompositions:

  • 47 + 2147525771 = 2147525818
  • 59 + 2147525759 = 2147525818
  • 89 + 2147525729 = 2147525818
  • 149 + 2147525669 = 2147525818
  • 521 + 2147525297 = 2147525818
  • 761 + 2147525057 = 2147525818
  • 821 + 2147524997 = 2147525818
  • 947 + 2147524871 = 2147525818

Showing the first eight; more decompositions exist.
