Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532468, here are decompositions:

31 + 31532437 = 31532468
67 + 31532401 = 31532468
127 + 31532341 = 31532468
139 + 31532329 = 31532468
199 + 31532269 = 31532468
241 + 31532227 = 31532468
379 + 31532089 = 31532468
397 + 31532071 = 31532468

Showing the first eight; more decompositions exist.
