Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573274, here are decompositions:

13 + 31573261 = 31573274
151 + 31573123 = 31573274
163 + 31573111 = 31573274
181 + 31573093 = 31573274
331 + 31572943 = 31573274
373 + 31572901 = 31573274
433 + 31572841 = 31573274
541 + 31572733 = 31573274

Showing the first eight; more decompositions exist.
