Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537182, here are decompositions:

29 + 31537153 = 31537182
31 + 31537151 = 31537182
139 + 31537043 = 31537182
179 + 31537003 = 31537182
181 + 31537001 = 31537182
191 + 31536991 = 31537182
199 + 31536983 = 31537182
223 + 31536959 = 31537182

Showing the first eight; more decompositions exist.
