Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582926, here are decompositions:

13 + 31582913 = 31582926
19 + 31582907 = 31582926
29 + 31582897 = 31582926
79 + 31582847 = 31582926
103 + 31582823 = 31582926
107 + 31582819 = 31582926
149 + 31582777 = 31582926
197 + 31582729 = 31582926

Showing the first eight; more decompositions exist.
