Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577682, here are decompositions:

13 + 31577669 = 31577682
23 + 31577659 = 31577682
89 + 31577593 = 31577682
151 + 31577531 = 31577682
173 + 31577509 = 31577682
211 + 31577471 = 31577682
281 + 31577401 = 31577682
293 + 31577389 = 31577682

Showing the first eight; more decompositions exist.
