Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613526, here are decompositions:

13 + 31613513 = 31613526
89 + 31613437 = 31613526
127 + 31613399 = 31613526
149 + 31613377 = 31613526
193 + 31613333 = 31613526
277 + 31613249 = 31613526
283 + 31613243 = 31613526
383 + 31613143 = 31613526

Showing the first eight; more decompositions exist.
