Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489404, here are decompositions:

5 + 31489399 = 31489404
13 + 31489391 = 31489404
41 + 31489363 = 31489404
157 + 31489247 = 31489404
211 + 31489193 = 31489404
223 + 31489181 = 31489404
227 + 31489177 = 31489404
257 + 31489147 = 31489404

Showing the first eight; more decompositions exist.
