Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468458, here are decompositions:

  • 29 + 2147468429 = 2147468458
  • 41 + 2147468417 = 2147468458
  • 167 + 2147468291 = 2147468458
  • 227 + 2147468231 = 2147468458
  • 269 + 2147468189 = 2147468458
  • 389 + 2147468069 = 2147468458
  • 491 + 2147467967 = 2147468458
  • 587 + 2147467871 = 2147468458

Showing the first eight; more decompositions exist.
