Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582732, here are decompositions:

3 + 31582729 = 31582732
53 + 31582679 = 31582732
59 + 31582673 = 31582732
101 + 31582631 = 31582732
131 + 31582601 = 31582732
173 + 31582559 = 31582732
179 + 31582553 = 31582732
491 + 31582241 = 31582732

Showing the first eight; more decompositions exist.
