Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599104, here are decompositions:

3 + 31599101 = 31599104
151 + 31598953 = 31599104
157 + 31598947 = 31599104
181 + 31598923 = 31599104
193 + 31598911 = 31599104
241 + 31598863 = 31599104
421 + 31598683 = 31599104
457 + 31598647 = 31599104

Showing the first eight; more decompositions exist.
