Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609622, here are decompositions:

13 + 31609609 = 31609622
61 + 31609561 = 31609622
73 + 31609549 = 31609622
103 + 31609519 = 31609622
229 + 31609393 = 31609622
241 + 31609381 = 31609622
283 + 31609339 = 31609622
409 + 31609213 = 31609622

Showing the first eight; more decompositions exist.
