Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72942, here are decompositions:

5 + 72937 = 72942
11 + 72931 = 72942
19 + 72923 = 72942
31 + 72911 = 72942
41 + 72901 = 72942
53 + 72889 = 72942
59 + 72883 = 72942
71 + 72871 = 72942

Showing the first eight; more decompositions exist.
