Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611304, here are decompositions:

3 + 31611301 = 31611304
5 + 31611299 = 31611304
167 + 31611137 = 31611304
191 + 31611113 = 31611304
281 + 31611023 = 31611304
293 + 31611011 = 31611304
563 + 31610741 = 31611304
743 + 31610561 = 31611304

Showing the first eight; more decompositions exist.
