Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592584, here are decompositions:

17 + 31592567 = 31592584
53 + 31592531 = 31592584
131 + 31592453 = 31592584
137 + 31592447 = 31592584
167 + 31592417 = 31592584
173 + 31592411 = 31592584
227 + 31592357 = 31592584
293 + 31592291 = 31592584

Showing the first eight; more decompositions exist.
