Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593420, here are decompositions:

29 + 31593391 = 31593420
31 + 31593389 = 31593420
43 + 31593377 = 31593420
107 + 31593313 = 31593420
113 + 31593307 = 31593420
167 + 31593253 = 31593420
223 + 31593197 = 31593420
227 + 31593193 = 31593420

Showing the first eight; more decompositions exist.
