Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590064, here are decompositions:

3 + 31590061 = 31590064
53 + 31590011 = 31590064
83 + 31589981 = 31590064
173 + 31589891 = 31590064
197 + 31589867 = 31590064
293 + 31589771 = 31590064
353 + 31589711 = 31590064
431 + 31589633 = 31590064

Showing the first eight; more decompositions exist.
