Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489354, here are decompositions:

5 + 31489349 = 31489354
107 + 31489247 = 31489354
137 + 31489217 = 31489354
173 + 31489181 = 31489354
257 + 31489097 = 31489354
263 + 31489091 = 31489354
311 + 31489043 = 31489354
317 + 31489037 = 31489354

Showing the first eight; more decompositions exist.
