Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573174, here are decompositions:

11 + 31573163 = 31573174
23 + 31573151 = 31573174
41 + 31573133 = 31573174
47 + 31573127 = 31573174
71 + 31573103 = 31573174
137 + 31573037 = 31573174
167 + 31573007 = 31573174
233 + 31572941 = 31573174

Showing the first eight; more decompositions exist.
