Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592458, here are decompositions:

5 + 31592453 = 31592458
11 + 31592447 = 31592458
41 + 31592417 = 31592458
47 + 31592411 = 31592458
89 + 31592369 = 31592458
101 + 31592357 = 31592458
167 + 31592291 = 31592458
239 + 31592219 = 31592458

Showing the first eight; more decompositions exist.
