Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546982, here are decompositions:

13 + 31546969 = 31546982
73 + 31546909 = 31546982
139 + 31546843 = 31546982
151 + 31546831 = 31546982
193 + 31546789 = 31546982
223 + 31546759 = 31546982
241 + 31546741 = 31546982
349 + 31546633 = 31546982

Showing the first eight; more decompositions exist.
