Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155328, here are decompositions:

11 + 155317 = 155328
29 + 155299 = 155328
37 + 155291 = 155328
59 + 155269 = 155328
97 + 155231 = 155328
109 + 155219 = 155328
127 + 155201 = 155328
137 + 155191 = 155328

Showing the first eight; more decompositions exist.
