Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592644, here are decompositions:

3 + 31592641 = 31592644
23 + 31592621 = 31592644
113 + 31592531 = 31592644
191 + 31592453 = 31592644
197 + 31592447 = 31592644
227 + 31592417 = 31592644
233 + 31592411 = 31592644
353 + 31592291 = 31592644

Showing the first eight; more decompositions exist.
