Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590184, here are decompositions:

23 + 31590161 = 31590184
47 + 31590137 = 31590184
113 + 31590071 = 31590184
173 + 31590011 = 31590184
293 + 31589891 = 31590184
317 + 31589867 = 31590184
491 + 31589693 = 31590184
617 + 31589567 = 31590184

Showing the first eight; more decompositions exist.
