Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593462, here are decompositions:

71 + 31593391 = 31593462
73 + 31593389 = 31593462
149 + 31593313 = 31593462
163 + 31593299 = 31593462
211 + 31593251 = 31593462
269 + 31593193 = 31593462
353 + 31593109 = 31593462
431 + 31593031 = 31593462

Showing the first eight; more decompositions exist.
