Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497432, here are decompositions:

  • 29 + 2147497403 = 2147497432
  • 71 + 2147497361 = 2147497432
  • 83 + 2147497349 = 2147497432
  • 389 + 2147497043 = 2147497432
  • 461 + 2147496971 = 2147497432
  • 491 + 2147496941 = 2147497432
  • 569 + 2147496863 = 2147497432
  • 593 + 2147496839 = 2147497432

Showing the first eight; more decompositions exist.
