Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468342, here are decompositions:

  • 73 + 2147468269 = 2147468342
  • 109 + 2147468233 = 2147468342
  • 211 + 2147468131 = 2147468342
  • 223 + 2147468119 = 2147468342
  • 379 + 2147467963 = 2147468342
  • 421 + 2147467921 = 2147468342
  • 541 + 2147467801 = 2147468342
  • 631 + 2147467711 = 2147468342

Showing the first eight; more decompositions exist.
