Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489366, here are decompositions:

3 + 31489363 = 31489366
17 + 31489349 = 31489366
107 + 31489259 = 31489366
137 + 31489229 = 31489366
149 + 31489217 = 31489366
173 + 31489193 = 31489366
197 + 31489169 = 31489366
269 + 31489097 = 31489366

Showing the first eight; more decompositions exist.
