Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155016, here are decompositions:

7 + 155009 = 155016
13 + 155003 = 155016
73 + 154943 = 155016
79 + 154937 = 155016
83 + 154933 = 155016
89 + 154927 = 155016
139 + 154877 = 155016
167 + 154849 = 155016

Showing the first eight; more decompositions exist.
