Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606924, here are decompositions:

5 + 31606919 = 31606924
113 + 31606811 = 31606924
197 + 31606727 = 31606924
227 + 31606697 = 31606924
233 + 31606691 = 31606924
257 + 31606667 = 31606924
263 + 31606661 = 31606924
281 + 31606643 = 31606924

Showing the first eight; more decompositions exist.
