Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541352, here are decompositions:

5 + 31541347 = 31541352
71 + 31541281 = 31541352
83 + 31541269 = 31541352
109 + 31541243 = 31541352
173 + 31541179 = 31541352
179 + 31541173 = 31541352
191 + 31541161 = 31541352
211 + 31541141 = 31541352

Showing the first eight; more decompositions exist.
