Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592816, here are decompositions:

7 + 31592809 = 31592816
19 + 31592797 = 31592816
37 + 31592779 = 31592816
43 + 31592773 = 31592816
139 + 31592677 = 31592816
349 + 31592467 = 31592816
379 + 31592437 = 31592816
439 + 31592377 = 31592816

Showing the first eight; more decompositions exist.
