Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155298, here are decompositions:

7 + 155291 = 155298
29 + 155269 = 155298
47 + 155251 = 155298
67 + 155231 = 155298
79 + 155219 = 155298
89 + 155209 = 155298
97 + 155201 = 155298
107 + 155191 = 155298

Showing the first eight; more decompositions exist.
