Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573332, here are decompositions:

53 + 31573279 = 31573332
71 + 31573261 = 31573332
73 + 31573259 = 31573332
79 + 31573253 = 31573332
179 + 31573153 = 31573332
181 + 31573151 = 31573332
199 + 31573133 = 31573332
223 + 31573109 = 31573332

Showing the first eight; more decompositions exist.
