Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470852, here are decompositions:

5 + 31470847 = 31470852
19 + 31470833 = 31470852
29 + 31470823 = 31470852
53 + 31470799 = 31470852
59 + 31470793 = 31470852
71 + 31470781 = 31470852
131 + 31470721 = 31470852
151 + 31470701 = 31470852

Showing the first eight; more decompositions exist.
