Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627160, here are decompositions:

109 + 31627051 = 31627160
127 + 31627033 = 31627160
181 + 31626979 = 31627160
193 + 31626967 = 31627160
277 + 31626883 = 31627160
373 + 31626787 = 31627160
541 + 31626619 = 31627160
571 + 31626589 = 31627160

Showing the first eight; more decompositions exist.
