Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144426, here are decompositions:

13 + 144413 = 144426
17 + 144409 = 144426
19 + 144407 = 144426
43 + 144383 = 144426
47 + 144379 = 144426
103 + 144323 = 144426
127 + 144299 = 144426
137 + 144289 = 144426

Showing the first eight; more decompositions exist.
