Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524038, here are decompositions:

97 + 31523941 = 31524038
157 + 31523881 = 31524038
199 + 31523839 = 31524038
277 + 31523761 = 31524038
331 + 31523707 = 31524038
379 + 31523659 = 31524038
439 + 31523599 = 31524038
499 + 31523539 = 31524038

Showing the first eight; more decompositions exist.
