Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537444, here are decompositions:

11 + 31537433 = 31537444
53 + 31537391 = 31537444
131 + 31537313 = 31537444
137 + 31537307 = 31537444
173 + 31537271 = 31537444
293 + 31537151 = 31537444
311 + 31537133 = 31537444
317 + 31537127 = 31537444

Showing the first eight; more decompositions exist.
