Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623462, here are decompositions:

19 + 31623443 = 31623462
23 + 31623439 = 31623462
41 + 31623421 = 31623462
89 + 31623373 = 31623462
239 + 31623223 = 31623462
251 + 31623211 = 31623462
263 + 31623199 = 31623462
281 + 31623181 = 31623462

Showing the first eight; more decompositions exist.
