Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468438, here are decompositions:

  • 7 + 2147468431 = 2147468438
  • 97 + 2147468341 = 2147468438
  • 307 + 2147468131 = 2147468438
  • 691 + 2147467747 = 2147468438
  • 727 + 2147467711 = 2147468438
  • 769 + 2147467669 = 2147468438
  • 811 + 2147467627 = 2147468438
  • 859 + 2147467579 = 2147468438

Showing the first eight; more decompositions exist.
