Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613522, here are decompositions:

139 + 31613383 = 31613522
181 + 31613341 = 31613522
331 + 31613191 = 31613522
379 + 31613143 = 31613522
541 + 31612981 = 31613522
571 + 31612951 = 31613522
631 + 31612891 = 31613522
691 + 31612831 = 31613522

Showing the first eight; more decompositions exist.
