Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480148, here are decompositions:

  • 109 + 2147480039 = 2147480148
  • 137 + 2147480011 = 2147480148
  • 139 + 2147480009 = 2147480148
  • 157 + 2147479991 = 2147480148
  • 211 + 2147479937 = 2147480148
  • 241 + 2147479907 = 2147480148
  • 251 + 2147479897 = 2147480148
  • 257 + 2147479891 = 2147480148

Showing the first eight; more decompositions exist.
