Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610550, here are decompositions:

11 + 31610539 = 31610550
29 + 31610521 = 31610550
31 + 31610519 = 31610550
47 + 31610503 = 31610550
113 + 31610437 = 31610550
137 + 31610413 = 31610550
157 + 31610393 = 31610550
197 + 31610353 = 31610550

Showing the first eight; more decompositions exist.
