Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468078, here are decompositions:

  • 157 + 2147467921 = 2147468078
  • 277 + 2147467801 = 2147468078
  • 331 + 2147467747 = 2147468078
  • 367 + 2147467711 = 2147468078
  • 409 + 2147467669 = 2147468078
  • 439 + 2147467639 = 2147468078
  • 499 + 2147467579 = 2147468078
  • 607 + 2147467471 = 2147468078

Showing the first eight; more decompositions exist.
