Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468660, here are decompositions:

  • 61 + 2147468599 = 2147468660
  • 97 + 2147468563 = 2147468660
  • 157 + 2147468503 = 2147468660
  • 163 + 2147468497 = 2147468660
  • 229 + 2147468431 = 2147468660
  • 487 + 2147468173 = 2147468660
  • 541 + 2147468119 = 2147468660
  • 739 + 2147467921 = 2147468660

Showing the first eight; more decompositions exist.
