Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468198, here are decompositions:

  • 67 + 2147468131 = 2147468198
  • 79 + 2147468119 = 2147468198
  • 277 + 2147467921 = 2147468198
  • 397 + 2147467801 = 2147468198
  • 439 + 2147467759 = 2147468198
  • 487 + 2147467711 = 2147468198
  • 571 + 2147467627 = 2147468198
  • 619 + 2147467579 = 2147468198

Showing the first eight; more decompositions exist.
