Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606674, here are decompositions:

7 + 31606667 = 31606674
13 + 31606661 = 31606674
17 + 31606657 = 31606674
23 + 31606651 = 31606674
31 + 31606643 = 31606674
131 + 31606543 = 31606674
137 + 31606537 = 31606674
157 + 31606517 = 31606674

Showing the first eight; more decompositions exist.
