Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489336, here are decompositions:

89 + 31489247 = 31489336
107 + 31489229 = 31489336
167 + 31489169 = 31489336
239 + 31489097 = 31489336
257 + 31489079 = 31489336
293 + 31489043 = 31489336
419 + 31488917 = 31489336
509 + 31488827 = 31489336

Showing the first eight; more decompositions exist.
