Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528202, here are decompositions:

31 + 31528171 = 31528202
109 + 31528093 = 31528202
271 + 31527931 = 31528202
373 + 31527829 = 31528202
421 + 31527781 = 31528202
499 + 31527703 = 31528202
619 + 31527583 = 31528202
661 + 31527541 = 31528202

Showing the first eight; more decompositions exist.
