Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577662, here are decompositions:

3 + 31577659 = 31577662
5 + 31577657 = 31577662
29 + 31577633 = 31577662
71 + 31577591 = 31577662
131 + 31577531 = 31577662
191 + 31577471 = 31577662
269 + 31577393 = 31577662
293 + 31577369 = 31577662

Showing the first eight; more decompositions exist.
