Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599248, here are decompositions:

337 + 31598911 = 31599248
409 + 31598839 = 31599248
547 + 31598701 = 31599248
601 + 31598647 = 31599248
727 + 31598521 = 31599248
829 + 31598419 = 31599248
1009 + 31598239 = 31599248
1021 + 31598227 = 31599248

Showing the first eight; more decompositions exist.
