Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590298, here are decompositions:

29 + 31590269 = 31590298
137 + 31590161 = 31590298
149 + 31590149 = 31590298
227 + 31590071 = 31590298
317 + 31589981 = 31590298
431 + 31589867 = 31590298
479 + 31589819 = 31590298
521 + 31589777 = 31590298

Showing the first eight; more decompositions exist.
