Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577676, here are decompositions:

7 + 31577669 = 31577676
17 + 31577659 = 31577676
19 + 31577657 = 31577676
29 + 31577647 = 31577676
43 + 31577633 = 31577676
83 + 31577593 = 31577676
89 + 31577587 = 31577676
149 + 31577527 = 31577676

Showing the first eight; more decompositions exist.
