Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532394, here are decompositions:

41 + 31532353 = 31532394
53 + 31532341 = 31532394
71 + 31532323 = 31532394
167 + 31532227 = 31532394
191 + 31532203 = 31532394
227 + 31532167 = 31532394
277 + 31532117 = 31532394
281 + 31532113 = 31532394

Showing the first eight; more decompositions exist.
