Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527204, here are decompositions:

11 + 31527193 = 31527204
13 + 31527191 = 31527204
31 + 31527173 = 31527204
47 + 31527157 = 31527204
53 + 31527151 = 31527204
61 + 31527143 = 31527204
73 + 31527131 = 31527204
97 + 31527107 = 31527204

Showing the first eight; more decompositions exist.
