Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573368, here are decompositions:

5 + 31573363 = 31573368
7 + 31573361 = 31573368
11 + 31573357 = 31573368
89 + 31573279 = 31573368
107 + 31573261 = 31573368
109 + 31573259 = 31573368
157 + 31573211 = 31573368
179 + 31573189 = 31573368

Showing the first eight; more decompositions exist.
