Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582264, here are decompositions:

23 + 31582241 = 31582264
47 + 31582217 = 31582264
71 + 31582193 = 31582264
101 + 31582163 = 31582264
167 + 31582097 = 31582264
227 + 31582037 = 31582264
281 + 31581983 = 31582264
317 + 31581947 = 31582264

Showing the first eight; more decompositions exist.
