Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542908, here are decompositions:

31 + 31542877 = 31542908
79 + 31542829 = 31542908
97 + 31542811 = 31542908
109 + 31542799 = 31542908
181 + 31542727 = 31542908
211 + 31542697 = 31542908
277 + 31542631 = 31542908
349 + 31542559 = 31542908

Showing the first eight; more decompositions exist.
