Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489266, here are decompositions:

7 + 31489259 = 31489266
19 + 31489247 = 31489266
23 + 31489243 = 31489266
37 + 31489229 = 31489266
73 + 31489193 = 31489266
89 + 31489177 = 31489266
97 + 31489169 = 31489266
197 + 31489069 = 31489266

Showing the first eight; more decompositions exist.
