Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593422, here are decompositions:

31 + 31593391 = 31593422
79 + 31593343 = 31593422
109 + 31593313 = 31593422
229 + 31593193 = 31593422
313 + 31593109 = 31593422
439 + 31592983 = 31593422
463 + 31592959 = 31593422
499 + 31592923 = 31593422

Showing the first eight; more decompositions exist.
