Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471652, here are decompositions:

13 + 31471639 = 31471652
19 + 31471633 = 31471652
31 + 31471621 = 31471652
61 + 31471591 = 31471652
73 + 31471579 = 31471652
103 + 31471549 = 31471652
241 + 31471411 = 31471652
439 + 31471213 = 31471652

Showing the first eight; more decompositions exist.
