Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590004, here are decompositions:

23 + 31589981 = 31590004
113 + 31589891 = 31590004
137 + 31589867 = 31590004
227 + 31589777 = 31590004
233 + 31589771 = 31590004
293 + 31589711 = 31590004
311 + 31589693 = 31590004
443 + 31589561 = 31590004

Showing the first eight; more decompositions exist.
