Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590232, here are decompositions:

71 + 31590161 = 31590232
83 + 31590149 = 31590232
251 + 31589981 = 31590232
389 + 31589843 = 31590232
461 + 31589771 = 31590232
521 + 31589711 = 31590232
599 + 31589633 = 31590232
719 + 31589513 = 31590232

Showing the first eight; more decompositions exist.
