Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590364, here are decompositions:

11 + 31590353 = 31590364
101 + 31590263 = 31590364
227 + 31590137 = 31590364
293 + 31590071 = 31590364
353 + 31590011 = 31590364
383 + 31589981 = 31590364
503 + 31589861 = 31590364
521 + 31589843 = 31590364

Showing the first eight; more decompositions exist.
