Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606654, here are decompositions:

3 + 31606651 = 31606654
11 + 31606643 = 31606654
71 + 31606583 = 31606654
113 + 31606541 = 31606654
137 + 31606517 = 31606654
257 + 31606397 = 31606654
281 + 31606373 = 31606654
311 + 31606343 = 31606654

Showing the first eight; more decompositions exist.
