Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599080, here are decompositions:

127 + 31598953 = 31599080
157 + 31598923 = 31599080
193 + 31598887 = 31599080
223 + 31598857 = 31599080
241 + 31598839 = 31599080
379 + 31598701 = 31599080
397 + 31598683 = 31599080
433 + 31598647 = 31599080

Showing the first eight; more decompositions exist.
