Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473090, here are decompositions:

  • 29 + 2147473061 = 2147473090
  • 41 + 2147473049 = 2147473090
  • 131 + 2147472959 = 2147473090
  • 167 + 2147472923 = 2147473090
  • 173 + 2147472917 = 2147473090
  • 197 + 2147472893 = 2147473090
  • 227 + 2147472863 = 2147473090
  • 293 + 2147472797 = 2147473090

Showing the first eight; more decompositions exist.
