Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592680, here are decompositions:

3 + 31592677 = 31592680
17 + 31592663 = 31592680
29 + 31592651 = 31592680
59 + 31592621 = 31592680
113 + 31592567 = 31592680
149 + 31592531 = 31592680
191 + 31592489 = 31592680
227 + 31592453 = 31592680

Showing the first eight; more decompositions exist.
