Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582962, here are decompositions:

11 + 31582951 = 31582962
13 + 31582949 = 31582962
31 + 31582931 = 31582962
71 + 31582891 = 31582962
139 + 31582823 = 31582962
181 + 31582781 = 31582962
223 + 31582739 = 31582962
233 + 31582729 = 31582962

Showing the first eight; more decompositions exist.
