Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605622, here are decompositions:

3 + 31605619 = 31605622
29 + 31605593 = 31605622
71 + 31605551 = 31605622
131 + 31605491 = 31605622
179 + 31605443 = 31605622
311 + 31605311 = 31605622
359 + 31605263 = 31605622
383 + 31605239 = 31605622

Showing the first eight; more decompositions exist.
