Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524218, here are decompositions:

127 + 31524091 = 31524218
277 + 31523941 = 31524218
337 + 31523881 = 31524218
367 + 31523851 = 31524218
379 + 31523839 = 31524218
457 + 31523761 = 31524218
571 + 31523647 = 31524218
619 + 31523599 = 31524218

Showing the first eight; more decompositions exist.
