Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531682, here are decompositions:

3 + 31531679 = 31531682
43 + 31531639 = 31531682
103 + 31531579 = 31531682
199 + 31531483 = 31531682
211 + 31531471 = 31531682
229 + 31531453 = 31531682
283 + 31531399 = 31531682
313 + 31531369 = 31531682

Showing the first eight; more decompositions exist.
