Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606300, here are decompositions:

3 + 31606297 = 31606300
17 + 31606283 = 31606300
23 + 31606277 = 31606300
113 + 31606187 = 31606300
233 + 31606067 = 31606300
239 + 31606061 = 31606300
251 + 31606049 = 31606300
317 + 31605983 = 31606300

Showing the first eight; more decompositions exist.
