Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582930, here are decompositions:

17 + 31582913 = 31582930
23 + 31582907 = 31582930
83 + 31582847 = 31582930
107 + 31582823 = 31582930
149 + 31582781 = 31582930
173 + 31582757 = 31582930
191 + 31582739 = 31582930
251 + 31582679 = 31582930

Showing the first eight; more decompositions exist.
