Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593222, here are decompositions:

29 + 31593193 = 31593222
113 + 31593109 = 31593222
191 + 31593031 = 31593222
211 + 31593011 = 31593222
229 + 31592993 = 31593222
239 + 31592983 = 31593222
251 + 31592971 = 31593222
263 + 31592959 = 31593222

Showing the first eight; more decompositions exist.
