Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592704, here are decompositions:

41 + 31592663 = 31592704
53 + 31592651 = 31592704
83 + 31592621 = 31592704
137 + 31592567 = 31592704
173 + 31592531 = 31592704
251 + 31592453 = 31592704
257 + 31592447 = 31592704
281 + 31592423 = 31592704

Showing the first eight; more decompositions exist.
