Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590334, here are decompositions:

71 + 31590263 = 31590334
173 + 31590161 = 31590334
197 + 31590137 = 31590334
263 + 31590071 = 31590334
353 + 31589981 = 31590334
443 + 31589891 = 31590334
467 + 31589867 = 31590334
491 + 31589843 = 31590334

Showing the first eight; more decompositions exist.
