Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606276, here are decompositions:

89 + 31606187 = 31606276
179 + 31606097 = 31606276
197 + 31606079 = 31606276
227 + 31606049 = 31606276
293 + 31605983 = 31606276
347 + 31605929 = 31606276
467 + 31605809 = 31606276
503 + 31605773 = 31606276

Showing the first eight; more decompositions exist.
