Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573262, here are decompositions:

3 + 31573259 = 31573262
73 + 31573189 = 31573262
109 + 31573153 = 31573262
139 + 31573123 = 31573262
151 + 31573111 = 31573262
241 + 31573021 = 31573262
283 + 31572979 = 31573262
313 + 31572949 = 31573262

Showing the first eight; more decompositions exist.
