Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590274, here are decompositions:

5 + 31590269 = 31590274
11 + 31590263 = 31590274
113 + 31590161 = 31590274
137 + 31590137 = 31590274
263 + 31590011 = 31590274
293 + 31589981 = 31590274
383 + 31589891 = 31590274
431 + 31589843 = 31590274

Showing the first eight; more decompositions exist.
