Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155346, here are decompositions:

13 + 155333 = 155346
19 + 155327 = 155346
29 + 155317 = 155346
43 + 155303 = 155346
47 + 155299 = 155346
127 + 155219 = 155346
137 + 155209 = 155346
179 + 155167 = 155346

Showing the first eight; more decompositions exist.
