Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527144, here are decompositions:

13 + 31527131 = 31527144
37 + 31527107 = 31527144
67 + 31527077 = 31527144
97 + 31527047 = 31527144
127 + 31527017 = 31527144
191 + 31526953 = 31527144
223 + 31526921 = 31527144
241 + 31526903 = 31527144

Showing the first eight; more decompositions exist.
