Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606414, here are decompositions:

3 + 31606411 = 31606414
17 + 31606397 = 31606414
41 + 31606373 = 31606414
71 + 31606343 = 31606414
83 + 31606331 = 31606414
101 + 31606313 = 31606414
131 + 31606283 = 31606414
137 + 31606277 = 31606414

Showing the first eight; more decompositions exist.
