Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613524, here are decompositions:

11 + 31613513 = 31613524
83 + 31613441 = 31613524
113 + 31613411 = 31613524
167 + 31613357 = 31613524
191 + 31613333 = 31613524
233 + 31613291 = 31613524
281 + 31613243 = 31613524
353 + 31613171 = 31613524

Showing the first eight; more decompositions exist.
