Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525432, here are decompositions:

11 + 31525421 = 31525432
53 + 31525379 = 31525432
89 + 31525343 = 31525432
101 + 31525331 = 31525432
149 + 31525283 = 31525432
269 + 31525163 = 31525432
311 + 31525121 = 31525432
401 + 31525031 = 31525432

Showing the first eight; more decompositions exist.
