Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467732, here are decompositions:

5 + 31467727 = 31467732
11 + 31467721 = 31467732
13 + 31467719 = 31467732
41 + 31467691 = 31467732
139 + 31467593 = 31467732
173 + 31467559 = 31467732
181 + 31467551 = 31467732
193 + 31467539 = 31467732

Showing the first eight; more decompositions exist.
