Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573476, here are decompositions:

13 + 31573463 = 31573476
83 + 31573393 = 31573476
113 + 31573363 = 31573476
197 + 31573279 = 31573476
199 + 31573277 = 31573476
223 + 31573253 = 31573476
313 + 31573163 = 31573476
349 + 31573127 = 31573476

Showing the first eight; more decompositions exist.
