Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155046, here are decompositions:

19 + 155027 = 155046
29 + 155017 = 155046
37 + 155009 = 155046
43 + 155003 = 155046
103 + 154943 = 155046
109 + 154937 = 155046
113 + 154933 = 155046
149 + 154897 = 155046

Showing the first eight; more decompositions exist.
