Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573324, here are decompositions:

47 + 31573277 = 31573324
71 + 31573253 = 31573324
113 + 31573211 = 31573324
173 + 31573151 = 31573324
191 + 31573133 = 31573324
197 + 31573127 = 31573324
317 + 31573007 = 31573324
353 + 31572971 = 31573324

Showing the first eight; more decompositions exist.
