Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558462, here are decompositions:

29 + 31558433 = 31558462
71 + 31558391 = 31558462
83 + 31558379 = 31558462
179 + 31558283 = 31558462
233 + 31558229 = 31558462
239 + 31558223 = 31558462
251 + 31558211 = 31558462
263 + 31558199 = 31558462

Showing the first eight; more decompositions exist.
