Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613622, here are decompositions:

41 + 31613581 = 31613622
43 + 31613579 = 31613622
71 + 31613551 = 31613622
83 + 31613539 = 31613622
109 + 31613513 = 31613622
181 + 31613441 = 31613622
211 + 31613411 = 31613622
223 + 31613399 = 31613622

Showing the first eight; more decompositions exist.
