Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627770, here are decompositions:

7 + 31627763 = 31627770
17 + 31627753 = 31627770
19 + 31627751 = 31627770
43 + 31627727 = 31627770
131 + 31627639 = 31627770
193 + 31627577 = 31627770
197 + 31627573 = 31627770
211 + 31627559 = 31627770

Showing the first eight; more decompositions exist.
