Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154944, here are decompositions:

7 + 154937 = 154944
11 + 154933 = 154944
17 + 154927 = 154944
47 + 154897 = 154944
61 + 154883 = 154944
67 + 154877 = 154944
71 + 154873 = 154944
73 + 154871 = 154944

Showing the first eight; more decompositions exist.
