Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468622, here are decompositions:

  • 23 + 2147468599 = 2147468622
  • 31 + 2147468591 = 2147468622
  • 59 + 2147468563 = 2147468622
  • 179 + 2147468443 = 2147468622
  • 191 + 2147468431 = 2147468622
  • 193 + 2147468429 = 2147468622
  • 199 + 2147468423 = 2147468622
  • 281 + 2147468341 = 2147468622

Showing the first eight; more decompositions exist.
