Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470846, here are decompositions:

13 + 31470833 = 31470846
19 + 31470827 = 31470846
23 + 31470823 = 31470846
47 + 31470799 = 31470846
53 + 31470793 = 31470846
59 + 31470787 = 31470846
137 + 31470709 = 31470846
193 + 31470653 = 31470846

Showing the first eight; more decompositions exist.
