Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468430, here are decompositions:

  • 7 + 2147468423 = 2147468430
  • 13 + 2147468417 = 2147468430
  • 89 + 2147468341 = 2147468430
  • 113 + 2147468317 = 2147468430
  • 139 + 2147468291 = 2147468430
  • 181 + 2147468249 = 2147468430
  • 197 + 2147468233 = 2147468430
  • 199 + 2147468231 = 2147468430

Showing the first eight; more decompositions exist.
