Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613514, here are decompositions:

73 + 31613441 = 31613514
103 + 31613411 = 31613514
113 + 31613401 = 31613514
131 + 31613383 = 31613514
137 + 31613377 = 31613514
157 + 31613357 = 31613514
173 + 31613341 = 31613514
181 + 31613333 = 31613514

Showing the first eight; more decompositions exist.
