Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144420, here are decompositions:

7 + 144413 = 144420
11 + 144409 = 144420
13 + 144407 = 144420
37 + 144383 = 144420
41 + 144379 = 144420
71 + 144349 = 144420
79 + 144341 = 144420
97 + 144323 = 144420

Showing the first eight; more decompositions exist.
