Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467638, here are decompositions:

  • 7 + 2147467631 = 2147467638
  • 11 + 2147467627 = 2147467638
  • 59 + 2147467579 = 2147467638
  • 79 + 2147467559 = 2147467638
  • 167 + 2147467471 = 2147467638
  • 271 + 2147467367 = 2147467638
  • 307 + 2147467331 = 2147467638
  • 311 + 2147467327 = 2147467638

Showing the first eight; more decompositions exist.
