Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592812, here are decompositions:

3 + 31592809 = 31592812
149 + 31592663 = 31592812
191 + 31592621 = 31592812
281 + 31592531 = 31592812
359 + 31592453 = 31592812
389 + 31592423 = 31592812
401 + 31592411 = 31592812
443 + 31592369 = 31592812

Showing the first eight; more decompositions exist.
