Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489348, here are decompositions:

89 + 31489259 = 31489348
101 + 31489247 = 31489348
131 + 31489217 = 31489348
167 + 31489181 = 31489348
179 + 31489169 = 31489348
251 + 31489097 = 31489348
257 + 31489091 = 31489348
269 + 31489079 = 31489348

Showing the first eight; more decompositions exist.
