Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592836, here are decompositions:

3 + 31592833 = 31592836
89 + 31592747 = 31592836
173 + 31592663 = 31592836
269 + 31592567 = 31592836
347 + 31592489 = 31592836
383 + 31592453 = 31592836
389 + 31592447 = 31592836
419 + 31592417 = 31592836

Showing the first eight; more decompositions exist.
