Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606152, here are decompositions:

73 + 31606079 = 31606152
101 + 31606051 = 31606152
103 + 31606049 = 31606152
181 + 31605971 = 31606152
199 + 31605953 = 31606152
223 + 31605929 = 31606152
239 + 31605913 = 31606152
349 + 31605803 = 31606152

Showing the first eight; more decompositions exist.
