Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592986, here are decompositions:

3 + 31592983 = 31592986
137 + 31592849 = 31592986
239 + 31592747 = 31592986
419 + 31592567 = 31592986
563 + 31592423 = 31592986
569 + 31592417 = 31592986
617 + 31592369 = 31592986
773 + 31592213 = 31592986

Showing the first eight; more decompositions exist.
