Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619508, here are decompositions:

7 + 31619501 = 31619508
101 + 31619407 = 31619508
149 + 31619359 = 31619508
181 + 31619327 = 31619508
197 + 31619311 = 31619508
227 + 31619281 = 31619508
241 + 31619267 = 31619508
251 + 31619257 = 31619508

Showing the first eight; more decompositions exist.
