Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582098, here are decompositions:

5 + 31582093 = 31582098
61 + 31582037 = 31582098
71 + 31582027 = 31582098
101 + 31581997 = 31582098
137 + 31581961 = 31582098
151 + 31581947 = 31582098
239 + 31581859 = 31582098
281 + 31581817 = 31582098

Showing the first eight; more decompositions exist.
