Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533342, here are decompositions:

73 + 31533269 = 31533342
83 + 31533259 = 31533342
151 + 31533191 = 31533342
193 + 31533149 = 31533342
199 + 31533143 = 31533342
223 + 31533119 = 31533342
241 + 31533101 = 31533342
251 + 31533091 = 31533342

Showing the first eight; more decompositions exist.

IPv4 address
