Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573342, here are decompositions:

83 + 31573259 = 31573342
89 + 31573253 = 31573342
131 + 31573211 = 31573342
179 + 31573163 = 31573342
191 + 31573151 = 31573342
233 + 31573109 = 31573342
239 + 31573103 = 31573342
401 + 31572941 = 31573342

Showing the first eight; more decompositions exist.
