Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155292, here are decompositions:

23 + 155269 = 155292
41 + 155251 = 155292
61 + 155231 = 155292
73 + 155219 = 155292
83 + 155209 = 155292
89 + 155203 = 155292
101 + 155191 = 155292
131 + 155161 = 155292

Showing the first eight; more decompositions exist.
