Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613406, here are decompositions:

5 + 31613401 = 31613406
7 + 31613399 = 31613406
23 + 31613383 = 31613406
29 + 31613377 = 31613406
73 + 31613333 = 31613406
157 + 31613249 = 31613406
163 + 31613243 = 31613406
179 + 31613227 = 31613406

Showing the first eight; more decompositions exist.
