Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582852, here are decompositions:

5 + 31582847 = 31582852
29 + 31582823 = 31582852
71 + 31582781 = 31582852
113 + 31582739 = 31582852
173 + 31582679 = 31582852
179 + 31582673 = 31582852
239 + 31582613 = 31582852
251 + 31582601 = 31582852

Showing the first eight; more decompositions exist.
