Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527184, here are decompositions:

11 + 31527173 = 31527184
41 + 31527143 = 31527184
53 + 31527131 = 31527184
107 + 31527077 = 31527184
137 + 31527047 = 31527184
167 + 31527017 = 31527184
173 + 31527011 = 31527184
257 + 31526927 = 31527184

Showing the first eight; more decompositions exist.
