Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542204, here are decompositions:

7 + 31542197 = 31542204
41 + 31542163 = 31542204
101 + 31542103 = 31542204
137 + 31542067 = 31542204
167 + 31542037 = 31542204
173 + 31542031 = 31542204
181 + 31542023 = 31542204
191 + 31542013 = 31542204

Showing the first eight; more decompositions exist.
