Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592572, here are decompositions:

5 + 31592567 = 31592572
41 + 31592531 = 31592572
83 + 31592489 = 31592572
149 + 31592423 = 31592572
281 + 31592291 = 31592572
353 + 31592219 = 31592572
359 + 31592213 = 31592572
443 + 31592129 = 31592572

Showing the first eight; more decompositions exist.
