Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623338, here are decompositions:

127 + 31623211 = 31623338
139 + 31623199 = 31623338
157 + 31623181 = 31623338
277 + 31623061 = 31623338
379 + 31622959 = 31623338
457 + 31622881 = 31623338
709 + 31622629 = 31623338
739 + 31622599 = 31623338

Showing the first eight; more decompositions exist.
