Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470798, here are decompositions:

5 + 31470793 = 31470798
11 + 31470787 = 31470798
17 + 31470781 = 31470798
89 + 31470709 = 31470798
97 + 31470701 = 31470798
137 + 31470661 = 31470798
157 + 31470641 = 31470798
179 + 31470619 = 31470798

Showing the first eight; more decompositions exist.
