Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573474, here are decompositions:

11 + 31573463 = 31573474
47 + 31573427 = 31573474
83 + 31573391 = 31573474
113 + 31573361 = 31573474
197 + 31573277 = 31573474
263 + 31573211 = 31573474
311 + 31573163 = 31573474
347 + 31573127 = 31573474

Showing the first eight; more decompositions exist.
