Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558304, here are decompositions:

97 + 31558207 = 31558304
157 + 31558147 = 31558304
223 + 31558081 = 31558304
241 + 31558063 = 31558304
307 + 31557997 = 31558304
367 + 31557937 = 31558304
373 + 31557931 = 31558304
571 + 31557733 = 31558304

Showing the first eight; more decompositions exist.
