Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155352, here are decompositions:

19 + 155333 = 155352
53 + 155299 = 155352
61 + 155291 = 155352
83 + 155269 = 155352
101 + 155251 = 155352
149 + 155203 = 155352
151 + 155201 = 155352
181 + 155171 = 155352

Showing the first eight; more decompositions exist.
