Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624608, here are decompositions:

11 + 31624597 = 31624608
17 + 31624591 = 31624608
61 + 31624547 = 31624608
97 + 31624511 = 31624608
101 + 31624507 = 31624608
131 + 31624477 = 31624608
151 + 31624457 = 31624608
179 + 31624429 = 31624608

Showing the first eight; more decompositions exist.
