Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619346, here are decompositions:

19 + 31619327 = 31619346
79 + 31619267 = 31619346
89 + 31619257 = 31619346
137 + 31619209 = 31619346
139 + 31619207 = 31619346
163 + 31619183 = 31619346
167 + 31619179 = 31619346
223 + 31619123 = 31619346

Showing the first eight; more decompositions exist.
