Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501716, here are decompositions:

17 + 31501699 = 31501716
47 + 31501669 = 31501716
83 + 31501633 = 31501716
97 + 31501619 = 31501716
149 + 31501567 = 31501716
179 + 31501537 = 31501716
193 + 31501523 = 31501716
269 + 31501447 = 31501716

Showing the first eight; more decompositions exist.
