Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121152, here are decompositions:

13 + 121139 = 121152
29 + 121123 = 121152
71 + 121081 = 121152
89 + 121063 = 121152
113 + 121039 = 121152
131 + 121021 = 121152
139 + 121013 = 121152
151 + 121001 = 121152

Showing the first eight; more decompositions exist.
