Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522306, here are decompositions:

29 + 31522277 = 31522306
59 + 31522247 = 31522306
293 + 31522013 = 31522306
353 + 31521953 = 31522306
419 + 31521887 = 31522306
443 + 31521863 = 31522306
593 + 31521713 = 31522306
659 + 31521647 = 31522306

Showing the first eight; more decompositions exist.
