Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590244, here are decompositions:

3 + 31590241 = 31590244
83 + 31590161 = 31590244
107 + 31590137 = 31590244
173 + 31590071 = 31590244
233 + 31590011 = 31590244
263 + 31589981 = 31590244
353 + 31589891 = 31590244
383 + 31589861 = 31590244

Showing the first eight; more decompositions exist.
