Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619682, here are decompositions:

13 + 31619669 = 31619682
71 + 31619611 = 31619682
79 + 31619603 = 31619682
139 + 31619543 = 31619682
151 + 31619531 = 31619682
163 + 31619519 = 31619682
173 + 31619509 = 31619682
181 + 31619501 = 31619682

Showing the first eight; more decompositions exist.
