Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534428, here are decompositions:

5 + 31534423 = 31534428
17 + 31534411 = 31534428
59 + 31534369 = 31534428
127 + 31534301 = 31534428
131 + 31534297 = 31534428
157 + 31534271 = 31534428
181 + 31534247 = 31534428
197 + 31534231 = 31534428

Showing the first eight; more decompositions exist.
