Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606054, here are decompositions:

3 + 31606051 = 31606054
5 + 31606049 = 31606054
71 + 31605983 = 31606054
83 + 31605971 = 31606054
101 + 31605953 = 31606054
251 + 31605803 = 31606054
281 + 31605773 = 31606054
353 + 31605701 = 31606054

Showing the first eight; more decompositions exist.
