Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473528, here are decompositions:

  • 41 + 2147473487 = 2147473528
  • 59 + 2147473469 = 2147473528
  • 197 + 2147473331 = 2147473528
  • 227 + 2147473301 = 2147473528
  • 311 + 2147473217 = 2147473528
  • 401 + 2147473127 = 2147473528
  • 467 + 2147473061 = 2147473528
  • 479 + 2147473049 = 2147473528

Showing the first eight; more decompositions exist.
