Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573260, here are decompositions:

7 + 31573253 = 31573260
71 + 31573189 = 31573260
97 + 31573163 = 31573260
107 + 31573153 = 31573260
109 + 31573151 = 31573260
127 + 31573133 = 31573260
137 + 31573123 = 31573260
149 + 31573111 = 31573260

Showing the first eight; more decompositions exist.
