Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144168, here are decompositions:

5 + 144163 = 144168
7 + 144161 = 144168
29 + 144139 = 144168
97 + 144071 = 144168
107 + 144061 = 144168
131 + 144037 = 144168
137 + 144031 = 144168
191 + 143977 = 144168

Showing the first eight; more decompositions exist.
