Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576566, here are decompositions:

17 + 31576549 = 31576566
37 + 31576529 = 31576566
83 + 31576483 = 31576566
89 + 31576477 = 31576566
107 + 31576459 = 31576566
113 + 31576453 = 31576566
127 + 31576439 = 31576566
139 + 31576427 = 31576566

Showing the first eight; more decompositions exist.
