Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524188, here are decompositions:

97 + 31524091 = 31524188
139 + 31524049 = 31524188
271 + 31523917 = 31524188
307 + 31523881 = 31524188
337 + 31523851 = 31524188
349 + 31523839 = 31524188
439 + 31523749 = 31524188
541 + 31523647 = 31524188

Showing the first eight; more decompositions exist.
