Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522196, here are decompositions:

67 + 31522129 = 31522196
313 + 31521883 = 31522196
367 + 31521829 = 31522196
457 + 31521739 = 31522196
523 + 31521673 = 31522196
547 + 31521649 = 31522196
757 + 31521439 = 31522196
787 + 31521409 = 31522196

Showing the first eight; more decompositions exist.
