Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468548, here are decompositions:

  • 11 + 2147468537 = 2147468548
  • 41 + 2147468507 = 2147468548
  • 131 + 2147468417 = 2147468548
  • 257 + 2147468291 = 2147468548
  • 317 + 2147468231 = 2147468548
  • 359 + 2147468189 = 2147468548
  • 479 + 2147468069 = 2147468548
  • 677 + 2147467871 = 2147468548

Showing the first eight; more decompositions exist.
