Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522136, here are decompositions:

7 + 31522129 = 31522136
157 + 31521979 = 31522136
307 + 31521829 = 31522136
397 + 31521739 = 31522136
463 + 31521673 = 31522136
487 + 31521649 = 31522136
577 + 31521559 = 31522136
727 + 31521409 = 31522136

Showing the first eight; more decompositions exist.
