Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155082, here are decompositions:

13 + 155069 = 155082
73 + 155009 = 155082
79 + 155003 = 155082
101 + 154981 = 155082
139 + 154943 = 155082
149 + 154933 = 155082
199 + 154883 = 155082
211 + 154871 = 155082

Showing the first eight; more decompositions exist.
