Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623374, here are decompositions:

31 + 31623343 = 31623374
37 + 31623337 = 31623374
151 + 31623223 = 31623374
163 + 31623211 = 31623374
193 + 31623181 = 31623374
313 + 31623061 = 31623374
571 + 31622803 = 31623374
631 + 31622743 = 31623374

Showing the first eight; more decompositions exist.
