Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471610, here are decompositions:

19 + 31471591 = 31471610
31 + 31471579 = 31471610
61 + 31471549 = 31471610
199 + 31471411 = 31471610
223 + 31471387 = 31471610
397 + 31471213 = 31471610
439 + 31471171 = 31471610
463 + 31471147 = 31471610

Showing the first eight; more decompositions exist.
