Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582804, here are decompositions:

23 + 31582781 = 31582804
47 + 31582757 = 31582804
131 + 31582673 = 31582804
137 + 31582667 = 31582804
173 + 31582631 = 31582804
191 + 31582613 = 31582804
251 + 31582553 = 31582804
257 + 31582547 = 31582804

Showing the first eight; more decompositions exist.
