Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593252, here are decompositions:

59 + 31593193 = 31593252
79 + 31593173 = 31593252
241 + 31593011 = 31593252
269 + 31592983 = 31593252
281 + 31592971 = 31593252
293 + 31592959 = 31593252
331 + 31592921 = 31593252
409 + 31592843 = 31593252

Showing the first eight; more decompositions exist.
