Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497528, here are decompositions:

  • 5 + 2147497523 = 2147497528
  • 47 + 2147497481 = 2147497528
  • 167 + 2147497361 = 2147497528
  • 179 + 2147497349 = 2147497528
  • 509 + 2147497019 = 2147497528
  • 557 + 2147496971 = 2147497528
  • 587 + 2147496941 = 2147497528
  • 797 + 2147496731 = 2147497528

Showing the first eight; more decompositions exist.
