Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593402, here are decompositions:

11 + 31593391 = 31593402
13 + 31593389 = 31593402
59 + 31593343 = 31593402
89 + 31593313 = 31593402
103 + 31593299 = 31593402
149 + 31593253 = 31593402
151 + 31593251 = 31593402
229 + 31593173 = 31593402

Showing the first eight; more decompositions exist.
