Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593000, here are decompositions:

7 + 31592993 = 31593000
17 + 31592983 = 31593000
29 + 31592971 = 31593000
41 + 31592959 = 31593000
53 + 31592947 = 31593000
79 + 31592921 = 31593000
151 + 31592849 = 31593000
157 + 31592843 = 31593000

Showing the first eight; more decompositions exist.
