Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522694, here are decompositions:

31 + 31522663 = 31522694
37 + 31522657 = 31522694
61 + 31522633 = 31522694
97 + 31522597 = 31522694
103 + 31522591 = 31522694
283 + 31522411 = 31522694
331 + 31522363 = 31522694
337 + 31522357 = 31522694

Showing the first eight; more decompositions exist.
