Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468632, here are decompositions:

  • 11 + 2147468621 = 2147468632
  • 41 + 2147468591 = 2147468632
  • 383 + 2147468249 = 2147468632
  • 401 + 2147468231 = 2147468632
  • 443 + 2147468189 = 2147468632
  • 563 + 2147468069 = 2147468632
  • 761 + 2147467871 = 2147468632
  • 839 + 2147467793 = 2147468632

Showing the first eight; more decompositions exist.
