Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543394, here are decompositions:

151 + 31543243 = 31543394
163 + 31543231 = 31543394
457 + 31542937 = 31543394
607 + 31542787 = 31543394
691 + 31542703 = 31543394
907 + 31542487 = 31543394
937 + 31542457 = 31543394
997 + 31542397 = 31543394

Showing the first eight; more decompositions exist.
