Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489426, here are decompositions:

167 + 31489259 = 31489426
179 + 31489247 = 31489426
197 + 31489229 = 31489426
233 + 31489193 = 31489426
257 + 31489169 = 31489426
347 + 31489079 = 31489426
383 + 31489043 = 31489426
389 + 31489037 = 31489426

Showing the first eight; more decompositions exist.
