Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627710, here are decompositions:

61 + 31627649 = 31627710
71 + 31627639 = 31627710
83 + 31627627 = 31627710
109 + 31627601 = 31627710
137 + 31627573 = 31627710
151 + 31627559 = 31627710
167 + 31627543 = 31627710
173 + 31627537 = 31627710

Showing the first eight; more decompositions exist.
