Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144216, here are decompositions:

13 + 144203 = 144216
43 + 144173 = 144216
47 + 144169 = 144216
53 + 144163 = 144216
113 + 144103 = 144216
179 + 144037 = 144216
239 + 143977 = 144216
263 + 143953 = 144216

Showing the first eight; more decompositions exist.
