Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607202, here are decompositions:

101 + 31607101 = 31607202
163 + 31607039 = 31607202
223 + 31606979 = 31607202
229 + 31606973 = 31607202
239 + 31606963 = 31607202
251 + 31606951 = 31607202
271 + 31606931 = 31607202
283 + 31606919 = 31607202

Showing the first eight; more decompositions exist.
