Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548622, here are decompositions:

3 + 31548619 = 31548622
29 + 31548593 = 31548622
59 + 31548563 = 31548622
71 + 31548551 = 31548622
89 + 31548533 = 31548622
101 + 31548521 = 31548622
179 + 31548443 = 31548622
191 + 31548431 = 31548622

Showing the first eight; more decompositions exist.
