Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582968, here are decompositions:

7 + 31582961 = 31582968
17 + 31582951 = 31582968
19 + 31582949 = 31582968
31 + 31582937 = 31582968
37 + 31582931 = 31582968
61 + 31582907 = 31582968
71 + 31582897 = 31582968
149 + 31582819 = 31582968

Showing the first eight; more decompositions exist.
