Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606230, here are decompositions:

43 + 31606187 = 31606230
151 + 31606079 = 31606230
163 + 31606067 = 31606230
179 + 31606051 = 31606230
181 + 31606049 = 31606230
277 + 31605953 = 31606230
317 + 31605913 = 31606230
353 + 31605877 = 31606230

Showing the first eight; more decompositions exist.
