Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524488, here are decompositions:

19 + 31524469 = 31524488
157 + 31524331 = 31524488
211 + 31524277 = 31524488
397 + 31524091 = 31524488
439 + 31524049 = 31524488
547 + 31523941 = 31524488
571 + 31523917 = 31524488
607 + 31523881 = 31524488

Showing the first eight; more decompositions exist.
