Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606410, here are decompositions:

13 + 31606397 = 31606410
23 + 31606387 = 31606410
29 + 31606381 = 31606410
37 + 31606373 = 31606410
41 + 31606369 = 31606410
67 + 31606343 = 31606410
71 + 31606339 = 31606410
79 + 31606331 = 31606410

Showing the first eight; more decompositions exist.
