Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532336, here are decompositions:

7 + 31532329 = 31532336
13 + 31532323 = 31532336
67 + 31532269 = 31532336
109 + 31532227 = 31532336
127 + 31532209 = 31532336
223 + 31532113 = 31532336
523 + 31531813 = 31532336
709 + 31531627 = 31532336

Showing the first eight; more decompositions exist.
