Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522046, here are decompositions:

67 + 31521979 = 31522046
163 + 31521883 = 31522046
307 + 31521739 = 31522046
373 + 31521673 = 31522046
379 + 31521667 = 31522046
397 + 31521649 = 31522046
487 + 31521559 = 31522046
547 + 31521499 = 31522046

Showing the first eight; more decompositions exist.
