Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519682, here are decompositions:

3 + 31519679 = 31519682
151 + 31519531 = 31519682
163 + 31519519 = 31519682
199 + 31519483 = 31519682
223 + 31519459 = 31519682
241 + 31519441 = 31519682
541 + 31519141 = 31519682
613 + 31519069 = 31519682

Showing the first eight; more decompositions exist.
