Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524620, here are decompositions:

13 + 31524607 = 31524620
79 + 31524541 = 31524620
97 + 31524523 = 31524620
103 + 31524517 = 31524620
151 + 31524469 = 31524620
277 + 31524343 = 31524620
349 + 31524271 = 31524620
397 + 31524223 = 31524620

Showing the first eight; more decompositions exist.
