Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489314, here are decompositions:

67 + 31489247 = 31489314
71 + 31489243 = 31489314
97 + 31489217 = 31489314
137 + 31489177 = 31489314
167 + 31489147 = 31489314
223 + 31489091 = 31489314
251 + 31489063 = 31489314
271 + 31489043 = 31489314

Showing the first eight; more decompositions exist.
