Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529196, here are decompositions:

29 + 31529167 = 31529196
47 + 31529149 = 31529196
89 + 31529107 = 31529196
107 + 31529089 = 31529196
109 + 31529087 = 31529196
199 + 31528997 = 31529196
227 + 31528969 = 31529196
229 + 31528967 = 31529196

Showing the first eight; more decompositions exist.
