Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144396, here are decompositions:

13 + 144383 = 144396
17 + 144379 = 144396
47 + 144349 = 144396
73 + 144323 = 144396
89 + 144307 = 144396
97 + 144299 = 144396
107 + 144289 = 144396
137 + 144259 = 144396

Showing the first eight; more decompositions exist.
