Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592776, here are decompositions:

3 + 31592773 = 31592776
29 + 31592747 = 31592776
113 + 31592663 = 31592776
353 + 31592423 = 31592776
359 + 31592417 = 31592776
419 + 31592357 = 31592776
557 + 31592219 = 31592776
563 + 31592213 = 31592776

Showing the first eight; more decompositions exist.
