Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606234, here are decompositions:

47 + 31606187 = 31606234
53 + 31606181 = 31606234
137 + 31606097 = 31606234
167 + 31606067 = 31606234
173 + 31606061 = 31606234
251 + 31605983 = 31606234
263 + 31605971 = 31606234
281 + 31605953 = 31606234

Showing the first eight; more decompositions exist.
