Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623368, here are decompositions:

31 + 31623337 = 31623368
157 + 31623211 = 31623368
199 + 31623169 = 31623368
307 + 31623061 = 31623368
409 + 31622959 = 31623368
421 + 31622947 = 31623368
487 + 31622881 = 31623368
727 + 31622641 = 31623368

Showing the first eight; more decompositions exist.
