Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613562, here are decompositions:

11 + 31613551 = 31613562
23 + 31613539 = 31613562
151 + 31613411 = 31613562
163 + 31613399 = 31613562
179 + 31613383 = 31613562
229 + 31613333 = 31613562
271 + 31613291 = 31613562
313 + 31613249 = 31613562

Showing the first eight; more decompositions exist.
