Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527234, here are decompositions:

23 + 31527211 = 31527234
41 + 31527193 = 31527234
43 + 31527191 = 31527234
61 + 31527173 = 31527234
83 + 31527151 = 31527234
103 + 31527131 = 31527234
127 + 31527107 = 31527234
157 + 31527077 = 31527234

Showing the first eight; more decompositions exist.
