Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582074, here are decompositions:

31 + 31582043 = 31582074
37 + 31582037 = 31582074
47 + 31582027 = 31582074
53 + 31582021 = 31582074
71 + 31582003 = 31582074
101 + 31581973 = 31582074
113 + 31581961 = 31582074
127 + 31581947 = 31582074

Showing the first eight; more decompositions exist.
