Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522888, here are decompositions:

41 + 31522847 = 31522888
347 + 31522541 = 31522888
359 + 31522529 = 31522888
557 + 31522331 = 31522888
641 + 31522247 = 31522888
647 + 31522241 = 31522888
659 + 31522229 = 31522888
797 + 31522091 = 31522888

Showing the first eight; more decompositions exist.
