Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541682, here are decompositions:

5 + 31541677 = 31541682
23 + 31541659 = 31541682
31 + 31541651 = 31541682
71 + 31541611 = 31541682
101 + 31541581 = 31541682
113 + 31541569 = 31541682
173 + 31541509 = 31541682
199 + 31541483 = 31541682

Showing the first eight; more decompositions exist.
