Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582060, here are decompositions:

11 + 31582049 = 31582060
17 + 31582043 = 31582060
23 + 31582037 = 31582060
113 + 31581947 = 31582060
149 + 31581911 = 31582060
179 + 31581881 = 31582060
197 + 31581863 = 31582060
281 + 31581779 = 31582060

Showing the first eight; more decompositions exist.
