Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527244, here are decompositions:

11 + 31527233 = 31527244
53 + 31527191 = 31527244
71 + 31527173 = 31527244
101 + 31527143 = 31527244
113 + 31527131 = 31527244
137 + 31527107 = 31527244
167 + 31527077 = 31527244
197 + 31527047 = 31527244

Showing the first eight; more decompositions exist.
