Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471634, here are decompositions:

13 + 31471621 = 31471634
43 + 31471591 = 31471634
223 + 31471411 = 31471634
277 + 31471357 = 31471634
421 + 31471213 = 31471634
463 + 31471171 = 31471634
487 + 31471147 = 31471634
541 + 31471093 = 31471634

Showing the first eight; more decompositions exist.
