Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582894, here are decompositions:

3 + 31582891 = 31582894
47 + 31582847 = 31582894
71 + 31582823 = 31582894
113 + 31582781 = 31582894
137 + 31582757 = 31582894
227 + 31582667 = 31582894
263 + 31582631 = 31582894
281 + 31582613 = 31582894

Showing the first eight; more decompositions exist.
