Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532390, here are decompositions:

37 + 31532353 = 31532390
61 + 31532329 = 31532390
67 + 31532323 = 31532390
163 + 31532227 = 31532390
181 + 31532209 = 31532390
223 + 31532167 = 31532390
277 + 31532113 = 31532390
577 + 31531813 = 31532390

Showing the first eight; more decompositions exist.
