Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488226, here are decompositions:

23 + 31488203 = 31488226
89 + 31488137 = 31488226
137 + 31488089 = 31488226
167 + 31488059 = 31488226
173 + 31488053 = 31488226
233 + 31487993 = 31488226
269 + 31487957 = 31488226
353 + 31487873 = 31488226

Showing the first eight; more decompositions exist.
