Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593030, here are decompositions:

19 + 31593011 = 31593030
37 + 31592993 = 31593030
47 + 31592983 = 31593030
59 + 31592971 = 31593030
71 + 31592959 = 31593030
83 + 31592947 = 31593030
107 + 31592923 = 31593030
109 + 31592921 = 31593030

Showing the first eight; more decompositions exist.
