Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468942, here are decompositions:

  • 19 + 2147468923 = 2147468942
  • 61 + 2147468881 = 2147468942
  • 109 + 2147468833 = 2147468942
  • 139 + 2147468803 = 2147468942
  • 163 + 2147468779 = 2147468942
  • 379 + 2147468563 = 2147468942
  • 439 + 2147468503 = 2147468942
  • 499 + 2147468443 = 2147468942

Showing the first eight; more decompositions exist.
