Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623656, here are decompositions:

67 + 31623589 = 31623656
157 + 31623499 = 31623656
283 + 31623373 = 31623656
313 + 31623343 = 31623656
433 + 31623223 = 31623656
457 + 31623199 = 31623656
487 + 31623169 = 31623656
709 + 31622947 = 31623656

Showing the first eight; more decompositions exist.
