Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86426, here are decompositions:

3 + 86423 = 86426
13 + 86413 = 86426
37 + 86389 = 86426
73 + 86353 = 86426
103 + 86323 = 86426
139 + 86287 = 86426
157 + 86269 = 86426
163 + 86263 = 86426

Showing the first eight; more decompositions exist.
