Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468678, here are decompositions:

  • 79 + 2147468599 = 2147468678
  • 181 + 2147468497 = 2147468678
  • 337 + 2147468341 = 2147468678
  • 409 + 2147468269 = 2147468678
  • 547 + 2147468131 = 2147468678
  • 757 + 2147467921 = 2147468678
  • 877 + 2147467801 = 2147468678
  • 919 + 2147467759 = 2147468678

Showing the first eight; more decompositions exist.
