Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471694, here are decompositions:

13 + 31471681 = 31471694
31 + 31471663 = 31471694
61 + 31471633 = 31471694
73 + 31471621 = 31471694
103 + 31471591 = 31471694
283 + 31471411 = 31471694
307 + 31471387 = 31471694
337 + 31471357 = 31471694

Showing the first eight; more decompositions exist.
