Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484280, here are decompositions:

  • 3 + 2147484277 = 2147484280
  • 41 + 2147484239 = 2147484280
  • 47 + 2147484233 = 2147484280
  • 59 + 2147484221 = 2147484280
  • 83 + 2147484197 = 2147484280
  • 113 + 2147484167 = 2147484280
  • 197 + 2147484083 = 2147484280
  • 239 + 2147484041 = 2147484280

Showing the first eight; more decompositions exist.
