Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593006, here are decompositions:

13 + 31592993 = 31593006
23 + 31592983 = 31593006
47 + 31592959 = 31593006
59 + 31592947 = 31593006
83 + 31592923 = 31593006
157 + 31592849 = 31593006
163 + 31592843 = 31593006
173 + 31592833 = 31593006

Showing the first eight; more decompositions exist.
