Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532606, here are decompositions:

13 + 31532593 = 31532606
19 + 31532587 = 31532606
67 + 31532539 = 31532606
109 + 31532497 = 31532606
277 + 31532329 = 31532606
283 + 31532323 = 31532606
337 + 31532269 = 31532606
379 + 31532227 = 31532606

Showing the first eight; more decompositions exist.
