Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144198, here are decompositions:

29 + 144169 = 144198
31 + 144167 = 144198
37 + 144161 = 144198
59 + 144139 = 144198
127 + 144071 = 144198
137 + 144061 = 144198
167 + 144031 = 144198
199 + 143999 = 144198

Showing the first eight; more decompositions exist.
