Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613610, here are decompositions:

29 + 31613581 = 31613610
31 + 31613579 = 31613610
59 + 31613551 = 31613610
71 + 31613539 = 31613610
97 + 31613513 = 31613610
173 + 31613437 = 31613610
199 + 31613411 = 31613610
211 + 31613399 = 31613610

Showing the first eight; more decompositions exist.
