Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613590, here are decompositions:

11 + 31613579 = 31613590
149 + 31613441 = 31613590
179 + 31613411 = 31613590
191 + 31613399 = 31613590
233 + 31613357 = 31613590
257 + 31613333 = 31613590
347 + 31613243 = 31613590
419 + 31613171 = 31613590

Showing the first eight; more decompositions exist.
