Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593150, here are decompositions:

41 + 31593109 = 31593150
53 + 31593097 = 31593150
103 + 31593047 = 31593150
139 + 31593011 = 31593150
157 + 31592993 = 31593150
167 + 31592983 = 31593150
179 + 31592971 = 31593150
191 + 31592959 = 31593150

Showing the first eight; more decompositions exist.
