Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592494, here are decompositions:

5 + 31592489 = 31592494
41 + 31592453 = 31592494
47 + 31592447 = 31592494
71 + 31592423 = 31592494
83 + 31592411 = 31592494
137 + 31592357 = 31592494
281 + 31592213 = 31592494
443 + 31592051 = 31592494

Showing the first eight; more decompositions exist.
