Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144960, here are decompositions:

19 + 144941 = 144960
29 + 144931 = 144960
43 + 144917 = 144960
61 + 144899 = 144960
71 + 144889 = 144960
73 + 144887 = 144960
113 + 144847 = 144960
131 + 144829 = 144960

Showing the first eight; more decompositions exist.
