Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617544, here are decompositions:

11 + 31617533 = 31617544
41 + 31617503 = 31617544
47 + 31617497 = 31617544
83 + 31617461 = 31617544
113 + 31617431 = 31617544
131 + 31617413 = 31617544
137 + 31617407 = 31617544
173 + 31617371 = 31617544

Showing the first eight; more decompositions exist.
