Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590358, here are decompositions:

5 + 31590353 = 31590358
89 + 31590269 = 31590358
197 + 31590161 = 31590358
269 + 31590089 = 31590358
347 + 31590011 = 31590358
467 + 31589891 = 31590358
491 + 31589867 = 31590358
587 + 31589771 = 31590358

Showing the first eight; more decompositions exist.
