Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606522, here are decompositions:

5 + 31606517 = 31606522
23 + 31606499 = 31606522
29 + 31606493 = 31606522
53 + 31606469 = 31606522
149 + 31606373 = 31606522
179 + 31606343 = 31606522
191 + 31606331 = 31606522
239 + 31606283 = 31606522

Showing the first eight; more decompositions exist.
