Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592610, here are decompositions:

11 + 31592599 = 31592610
43 + 31592567 = 31592610
53 + 31592557 = 31592610
59 + 31592551 = 31592610
79 + 31592531 = 31592610
157 + 31592453 = 31592610
163 + 31592447 = 31592610
173 + 31592437 = 31592610

Showing the first eight; more decompositions exist.
