Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522106, here are decompositions:

3 + 31522103 = 31522106
127 + 31521979 = 31522106
223 + 31521883 = 31522106
277 + 31521829 = 31522106
313 + 31521793 = 31522106
367 + 31521739 = 31522106
433 + 31521673 = 31522106
439 + 31521667 = 31522106

Showing the first eight; more decompositions exist.
