Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613718, here are decompositions:

79 + 31613639 = 31613718
89 + 31613629 = 31613718
137 + 31613581 = 31613718
139 + 31613579 = 31613718
167 + 31613551 = 31613718
179 + 31613539 = 31613718
277 + 31613441 = 31613718
281 + 31613437 = 31613718

Showing the first eight; more decompositions exist.
