Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623494, here are decompositions:

3 + 31623491 = 31623494
13 + 31623481 = 31623494
73 + 31623421 = 31623494
151 + 31623343 = 31623494
157 + 31623337 = 31623494
271 + 31623223 = 31623494
283 + 31623211 = 31623494
313 + 31623181 = 31623494

Showing the first eight; more decompositions exist.
