Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537324, here are decompositions:

11 + 31537313 = 31537324
17 + 31537307 = 31537324
53 + 31537271 = 31537324
101 + 31537223 = 31537324
173 + 31537151 = 31537324
191 + 31537133 = 31537324
197 + 31537127 = 31537324
227 + 31537097 = 31537324

Showing the first eight; more decompositions exist.
