Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526132, here are decompositions:

151 + 31525981 = 31526132
181 + 31525951 = 31526132
223 + 31525909 = 31526132
229 + 31525903 = 31526132
241 + 31525891 = 31526132
283 + 31525849 = 31526132
349 + 31525783 = 31526132
409 + 31525723 = 31526132

Showing the first eight; more decompositions exist.
