Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470682, here are decompositions:

29 + 31470653 = 31470682
41 + 31470641 = 31470682
53 + 31470629 = 31470682
59 + 31470623 = 31470682
101 + 31470581 = 31470682
239 + 31470443 = 31470682
359 + 31470323 = 31470682
389 + 31470293 = 31470682

Showing the first eight; more decompositions exist.
