Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582174, here are decompositions:

3 + 31582171 = 31582174
11 + 31582163 = 31582174
53 + 31582121 = 31582174
131 + 31582043 = 31582174
137 + 31582037 = 31582174
191 + 31581983 = 31582174
227 + 31581947 = 31582174
263 + 31581911 = 31582174

Showing the first eight; more decompositions exist.
