Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613598, here are decompositions:

17 + 31613581 = 31613598
19 + 31613579 = 31613598
47 + 31613551 = 31613598
59 + 31613539 = 31613598
157 + 31613441 = 31613598
197 + 31613401 = 31613598
199 + 31613399 = 31613598
241 + 31613357 = 31613598

Showing the first eight; more decompositions exist.
