Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537464, here are decompositions:

31 + 31537433 = 31537464
73 + 31537391 = 31537464
137 + 31537327 = 31537464
151 + 31537313 = 31537464
157 + 31537307 = 31537464
191 + 31537273 = 31537464
193 + 31537271 = 31537464
197 + 31537267 = 31537464

Showing the first eight; more decompositions exist.
