Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573350, here are decompositions:

71 + 31573279 = 31573350
73 + 31573277 = 31573350
89 + 31573261 = 31573350
97 + 31573253 = 31573350
139 + 31573211 = 31573350
197 + 31573153 = 31573350
199 + 31573151 = 31573350
223 + 31573127 = 31573350

Showing the first eight; more decompositions exist.
