Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610574, here are decompositions:

5 + 31610569 = 31610574
11 + 31610563 = 31610574
13 + 31610561 = 31610574
53 + 31610521 = 31610574
71 + 31610503 = 31610574
137 + 31610437 = 31610574
181 + 31610393 = 31610574
211 + 31610363 = 31610574

Showing the first eight; more decompositions exist.
