Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613540, here are decompositions:

103 + 31613437 = 31613540
139 + 31613401 = 31613540
157 + 31613383 = 31613540
163 + 31613377 = 31613540
199 + 31613341 = 31613540
313 + 31613227 = 31613540
349 + 31613191 = 31613540
397 + 31613143 = 31613540

Showing the first eight; more decompositions exist.
