Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619588, here are decompositions:

31 + 31619557 = 31619588
61 + 31619527 = 31619588
67 + 31619521 = 31619588
79 + 31619509 = 31619588
181 + 31619407 = 31619588
199 + 31619389 = 31619588
229 + 31619359 = 31619588
277 + 31619311 = 31619588

Showing the first eight; more decompositions exist.
