Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627676, here are decompositions:

37 + 31627639 = 31627676
103 + 31627573 = 31627676
109 + 31627567 = 31627676
139 + 31627537 = 31627676
193 + 31627483 = 31627676
373 + 31627303 = 31627676
433 + 31627243 = 31627676
439 + 31627237 = 31627676

Showing the first eight; more decompositions exist.
