Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144042, here are decompositions:

5 + 144037 = 144042
11 + 144031 = 144042
29 + 144013 = 144042
43 + 143999 = 144042
61 + 143981 = 144042
71 + 143971 = 144042
89 + 143953 = 144042
163 + 143879 = 144042

Showing the first eight; more decompositions exist.
