Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592854, here are decompositions:

5 + 31592849 = 31592854
11 + 31592843 = 31592854
107 + 31592747 = 31592854
191 + 31592663 = 31592854
233 + 31592621 = 31592854
401 + 31592453 = 31592854
431 + 31592423 = 31592854
443 + 31592411 = 31592854

Showing the first eight; more decompositions exist.
