Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72042, here are decompositions:

11 + 72031 = 72042
23 + 72019 = 72042
43 + 71999 = 72042
59 + 71983 = 72042
71 + 71971 = 72042
79 + 71963 = 72042
101 + 71941 = 72042
109 + 71933 = 72042

Showing the first eight; more decompositions exist.
