Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468618, here are decompositions:

  • 19 + 2147468599 = 2147468618
  • 277 + 2147468341 = 2147468618
  • 349 + 2147468269 = 2147468618
  • 487 + 2147468131 = 2147468618
  • 499 + 2147468119 = 2147468618
  • 859 + 2147467759 = 2147468618
  • 907 + 2147467711 = 2147468618
  • 991 + 2147467627 = 2147468618

Showing the first eight; more decompositions exist.
