Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606416, here are decompositions:

5 + 31606411 = 31606416
19 + 31606397 = 31606416
29 + 31606387 = 31606416
43 + 31606373 = 31606416
47 + 31606369 = 31606416
73 + 31606343 = 31606416
97 + 31606319 = 31606416
103 + 31606313 = 31606416

Showing the first eight; more decompositions exist.
