Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606710, here are decompositions:

7 + 31606703 = 31606710
13 + 31606697 = 31606710
19 + 31606691 = 31606710
29 + 31606681 = 31606710
43 + 31606667 = 31606710
53 + 31606657 = 31606710
59 + 31606651 = 31606710
67 + 31606643 = 31606710

Showing the first eight; more decompositions exist.
