Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532234, here are decompositions:

7 + 31532227 = 31532234
31 + 31532203 = 31532234
67 + 31532167 = 31532234
163 + 31532071 = 31532234
313 + 31531921 = 31532234
421 + 31531813 = 31532234
607 + 31531627 = 31532234
751 + 31531483 = 31532234

Showing the first eight; more decompositions exist.
