Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582534, here are decompositions:

3 + 31582531 = 31582534
131 + 31582403 = 31582534
197 + 31582337 = 31582534
293 + 31582241 = 31582534
317 + 31582217 = 31582534
491 + 31582043 = 31582534
587 + 31581947 = 31582534
653 + 31581881 = 31582534

Showing the first eight; more decompositions exist.
