Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593210, here are decompositions:

13 + 31593197 = 31593210
17 + 31593193 = 31593210
37 + 31593173 = 31593210
101 + 31593109 = 31593210
113 + 31593097 = 31593210
163 + 31593047 = 31593210
179 + 31593031 = 31593210
199 + 31593011 = 31593210

Showing the first eight; more decompositions exist.
