Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610532, here are decompositions:

11 + 31610521 = 31610532
13 + 31610519 = 31610532
29 + 31610503 = 31610532
139 + 31610393 = 31610532
179 + 31610353 = 31610532
193 + 31610339 = 31610532
199 + 31610333 = 31610532
241 + 31610291 = 31610532

Showing the first eight; more decompositions exist.
