Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606612, here are decompositions:

29 + 31606583 = 31606612
53 + 31606559 = 31606612
71 + 31606541 = 31606612
83 + 31606529 = 31606612
113 + 31606499 = 31606612
239 + 31606373 = 31606612
269 + 31606343 = 31606612
281 + 31606331 = 31606612

Showing the first eight; more decompositions exist.
