Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590436, here are decompositions:

23 + 31590413 = 31590436
83 + 31590353 = 31590436
167 + 31590269 = 31590436
173 + 31590263 = 31590436
347 + 31590089 = 31590436
569 + 31589867 = 31590436
593 + 31589843 = 31590436
617 + 31589819 = 31590436

Showing the first eight; more decompositions exist.
