Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156426, here are decompositions:

5 + 156421 = 156426
7 + 156419 = 156426
73 + 156353 = 156426
79 + 156347 = 156426
97 + 156329 = 156426
107 + 156319 = 156426
157 + 156269 = 156426
167 + 156259 = 156426

Showing the first eight; more decompositions exist.
