Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532478, here are decompositions:

41 + 31532437 = 31532478
137 + 31532341 = 31532478
139 + 31532339 = 31532478
149 + 31532329 = 31532478
199 + 31532279 = 31532478
251 + 31532227 = 31532478
269 + 31532209 = 31532478
311 + 31532167 = 31532478

Showing the first eight; more decompositions exist.
