Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468168, here are decompositions:

  • 37 + 2147468131 = 2147468168
  • 367 + 2147467801 = 2147468168
  • 409 + 2147467759 = 2147468168
  • 421 + 2147467747 = 2147468168
  • 457 + 2147467711 = 2147468168
  • 499 + 2147467669 = 2147468168
  • 541 + 2147467627 = 2147468168
  • 829 + 2147467339 = 2147468168

Showing the first eight; more decompositions exist.
