Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622074, here are decompositions:

173 + 31621901 = 31622074
227 + 31621847 = 31622074
401 + 31621673 = 31622074
443 + 31621631 = 31622074
461 + 31621613 = 31622074
557 + 31621517 = 31622074
587 + 31621487 = 31622074
647 + 31621427 = 31622074

Showing the first eight; more decompositions exist.
