Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613506, here are decompositions:

107 + 31613399 = 31613506
149 + 31613357 = 31613506
173 + 31613333 = 31613506
257 + 31613249 = 31613506
263 + 31613243 = 31613506
389 + 31613117 = 31613506
479 + 31613027 = 31613506
593 + 31612913 = 31613506

Showing the first eight; more decompositions exist.
