Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592848, here are decompositions:

5 + 31592843 = 31592848
101 + 31592747 = 31592848
197 + 31592651 = 31592848
227 + 31592621 = 31592848
281 + 31592567 = 31592848
317 + 31592531 = 31592848
359 + 31592489 = 31592848
401 + 31592447 = 31592848

Showing the first eight; more decompositions exist.
