Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592866, here are decompositions:

17 + 31592849 = 31592866
23 + 31592843 = 31592866
419 + 31592447 = 31592866
443 + 31592423 = 31592866
449 + 31592417 = 31592866
509 + 31592357 = 31592866
647 + 31592219 = 31592866
653 + 31592213 = 31592866

Showing the first eight; more decompositions exist.
