Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582054, here are decompositions:

5 + 31582049 = 31582054
11 + 31582043 = 31582054
17 + 31582037 = 31582054
71 + 31581983 = 31582054
107 + 31581947 = 31582054
173 + 31581881 = 31582054
191 + 31581863 = 31582054
293 + 31581761 = 31582054

Showing the first eight; more decompositions exist.
