Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590266, here are decompositions:

3 + 31590263 = 31590266
79 + 31590187 = 31590266
229 + 31590037 = 31590266
283 + 31589983 = 31590266
313 + 31589953 = 31590266
397 + 31589869 = 31590266
439 + 31589827 = 31590266
607 + 31589659 = 31590266

Showing the first eight; more decompositions exist.
