Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470792, here are decompositions:

5 + 31470787 = 31470792
11 + 31470781 = 31470792
71 + 31470721 = 31470792
83 + 31470709 = 31470792
131 + 31470661 = 31470792
139 + 31470653 = 31470792
151 + 31470641 = 31470792
163 + 31470629 = 31470792

Showing the first eight; more decompositions exist.
