Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54042, here are decompositions:

5 + 54037 = 54042
29 + 54013 = 54042
31 + 54011 = 54042
41 + 54001 = 54042
83 + 53959 = 54042
103 + 53939 = 54042
151 + 53891 = 54042
181 + 53861 = 54042

Showing the first eight; more decompositions exist.
