Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524818, here are decompositions:

97 + 31524721 = 31524818
211 + 31524607 = 31524818
277 + 31524541 = 31524818
349 + 31524469 = 31524818
487 + 31524331 = 31524818
541 + 31524277 = 31524818
547 + 31524271 = 31524818
727 + 31524091 = 31524818

Showing the first eight; more decompositions exist.
