Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144450, here are decompositions:

11 + 144439 = 144450
23 + 144427 = 144450
37 + 144413 = 144450
41 + 144409 = 144450
43 + 144407 = 144450
67 + 144383 = 144450
71 + 144379 = 144450
101 + 144349 = 144450

Showing the first eight; more decompositions exist.
