Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590058, here are decompositions:

47 + 31590011 = 31590058
167 + 31589891 = 31590058
191 + 31589867 = 31590058
197 + 31589861 = 31590058
239 + 31589819 = 31590058
281 + 31589777 = 31590058
347 + 31589711 = 31590058
491 + 31589567 = 31590058

Showing the first eight; more decompositions exist.
