Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470660, here are decompositions:

7 + 31470653 = 31470660
19 + 31470641 = 31470660
31 + 31470629 = 31470660
37 + 31470623 = 31470660
41 + 31470619 = 31470660
79 + 31470581 = 31470660
97 + 31470563 = 31470660
103 + 31470557 = 31470660

Showing the first eight; more decompositions exist.
