Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155050, here are decompositions:

3 + 155047 = 155050
23 + 155027 = 155050
41 + 155009 = 155050
47 + 155003 = 155050
59 + 154991 = 155050
107 + 154943 = 155050
113 + 154937 = 155050
167 + 154883 = 155050

Showing the first eight; more decompositions exist.
