Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606122, here are decompositions:

43 + 31606079 = 31606122
61 + 31606061 = 31606122
71 + 31606051 = 31606122
73 + 31606049 = 31606122
139 + 31605983 = 31606122
151 + 31605971 = 31606122
193 + 31605929 = 31606122
311 + 31605811 = 31606122

Showing the first eight; more decompositions exist.
