Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606246, here are decompositions:

59 + 31606187 = 31606246
149 + 31606097 = 31606246
167 + 31606079 = 31606246
179 + 31606067 = 31606246
197 + 31606049 = 31606246
263 + 31605983 = 31606246
293 + 31605953 = 31606246
317 + 31605929 = 31606246

Showing the first eight; more decompositions exist.
