Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627682, here are decompositions:

43 + 31627639 = 31627682
109 + 31627573 = 31627682
139 + 31627543 = 31627682
181 + 31627501 = 31627682
199 + 31627483 = 31627682
271 + 31627411 = 31627682
349 + 31627333 = 31627682
379 + 31627303 = 31627682

Showing the first eight; more decompositions exist.
