Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606162, here are decompositions:

83 + 31606079 = 31606162
101 + 31606061 = 31606162
113 + 31606049 = 31606162
179 + 31605983 = 31606162
191 + 31605971 = 31606162
233 + 31605929 = 31606162
353 + 31605809 = 31606162
359 + 31605803 = 31606162

Showing the first eight; more decompositions exist.
