Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613586, here are decompositions:

5 + 31613581 = 31613586
7 + 31613579 = 31613586
47 + 31613539 = 31613586
73 + 31613513 = 31613586
149 + 31613437 = 31613586
229 + 31613357 = 31613586
337 + 31613249 = 31613586
359 + 31613227 = 31613586

Showing the first eight; more decompositions exist.
