Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537344, here are decompositions:

5 + 31537339 = 31537344
17 + 31537327 = 31537344
31 + 31537313 = 31537344
37 + 31537307 = 31537344
71 + 31537273 = 31537344
73 + 31537271 = 31537344
101 + 31537243 = 31537344
191 + 31537153 = 31537344

Showing the first eight; more decompositions exist.
