Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573334, here are decompositions:

73 + 31573261 = 31573334
181 + 31573153 = 31573334
211 + 31573123 = 31573334
223 + 31573111 = 31573334
241 + 31573093 = 31573334
277 + 31573057 = 31573334
307 + 31573027 = 31573334
313 + 31573021 = 31573334

Showing the first eight; more decompositions exist.
