Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484156, here are decompositions:

  • 47 + 2147484109 = 2147484156
  • 73 + 2147484083 = 2147484156
  • 113 + 2147484043 = 2147484156
  • 149 + 2147484007 = 2147484156
  • 157 + 2147483999 = 2147484156
  • 163 + 2147483993 = 2147484156
  • 227 + 2147483929 = 2147484156
  • 263 + 2147483893 = 2147484156

Showing the first eight; more decompositions exist.

IPv4 address
