Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606614, here are decompositions:

31 + 31606583 = 31606614
71 + 31606543 = 31606614
73 + 31606541 = 31606614
97 + 31606517 = 31606614
191 + 31606423 = 31606614
227 + 31606387 = 31606614
233 + 31606381 = 31606614
241 + 31606373 = 31606614

Showing the first eight; more decompositions exist.
