Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619522, here are decompositions:

3 + 31619519 = 31619522
13 + 31619509 = 31619522
163 + 31619359 = 31619522
211 + 31619311 = 31619522
241 + 31619281 = 31619522
313 + 31619209 = 31619522
331 + 31619191 = 31619522
379 + 31619143 = 31619522

Showing the first eight; more decompositions exist.
