Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593404, here are decompositions:

13 + 31593391 = 31593404
61 + 31593343 = 31593404
97 + 31593307 = 31593404
151 + 31593253 = 31593404
211 + 31593193 = 31593404
307 + 31593097 = 31593404
373 + 31593031 = 31593404
421 + 31592983 = 31593404

Showing the first eight; more decompositions exist.
