Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613436, here are decompositions:

37 + 31613399 = 31613436
53 + 31613383 = 31613436
59 + 31613377 = 31613436
79 + 31613357 = 31613436
103 + 31613333 = 31613436
193 + 31613243 = 31613436
293 + 31613143 = 31613436
317 + 31613119 = 31613436

Showing the first eight; more decompositions exist.
