Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593432, here are decompositions:

41 + 31593391 = 31593432
43 + 31593389 = 31593432
89 + 31593343 = 31593432
179 + 31593253 = 31593432
181 + 31593251 = 31593432
239 + 31593193 = 31593432
401 + 31593031 = 31593432
421 + 31593011 = 31593432

Showing the first eight; more decompositions exist.
