Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599416, here are decompositions:

67 + 31599349 = 31599416
103 + 31599313 = 31599416
109 + 31599307 = 31599416
157 + 31599259 = 31599416
223 + 31599193 = 31599416
313 + 31599103 = 31599416
463 + 31598953 = 31599416
577 + 31598839 = 31599416

Showing the first eight; more decompositions exist.
