Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468954, here are decompositions:

  • 31 + 2147468923 = 2147468954
  • 67 + 2147468887 = 2147468954
  • 73 + 2147468881 = 2147468954
  • 151 + 2147468803 = 2147468954
  • 181 + 2147468773 = 2147468954
  • 457 + 2147468497 = 2147468954
  • 523 + 2147468431 = 2147468954
  • 613 + 2147468341 = 2147468954

Showing the first eight; more decompositions exist.
