Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593282, here are decompositions:

29 + 31593253 = 31593282
31 + 31593251 = 31593282
89 + 31593193 = 31593282
109 + 31593173 = 31593282
173 + 31593109 = 31593282
251 + 31593031 = 31593282
271 + 31593011 = 31593282
311 + 31592971 = 31593282

Showing the first eight; more decompositions exist.
