Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619484, here are decompositions:

97 + 31619387 = 31619484
157 + 31619327 = 31619484
173 + 31619311 = 31619484
223 + 31619261 = 31619484
227 + 31619257 = 31619484
271 + 31619213 = 31619484
277 + 31619207 = 31619484
293 + 31619191 = 31619484

Showing the first eight; more decompositions exist.
