Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582954, here are decompositions:

3 + 31582951 = 31582954
5 + 31582949 = 31582954
17 + 31582937 = 31582954
23 + 31582931 = 31582954
41 + 31582913 = 31582954
47 + 31582907 = 31582954
107 + 31582847 = 31582954
131 + 31582823 = 31582954

Showing the first eight; more decompositions exist.
