Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606548, here are decompositions:

5 + 31606543 = 31606548
7 + 31606541 = 31606548
11 + 31606537 = 31606548
19 + 31606529 = 31606548
31 + 31606517 = 31606548
79 + 31606469 = 31606548
137 + 31606411 = 31606548
151 + 31606397 = 31606548

Showing the first eight; more decompositions exist.
