Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522226, here are decompositions:

7 + 31522219 = 31522226
19 + 31522207 = 31522226
97 + 31522129 = 31522226
397 + 31521829 = 31522226
433 + 31521793 = 31522226
487 + 31521739 = 31522226
577 + 31521649 = 31522226
727 + 31521499 = 31522226

Showing the first eight; more decompositions exist.
