Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524278, here are decompositions:

7 + 31524271 = 31524278
229 + 31524049 = 31524278
337 + 31523941 = 31524278
397 + 31523881 = 31524278
439 + 31523839 = 31524278
571 + 31523707 = 31524278
619 + 31523659 = 31524278
631 + 31523647 = 31524278

Showing the first eight; more decompositions exist.
