Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51042, here are decompositions:

11 + 51031 = 51042
41 + 51001 = 51042
53 + 50989 = 51042
71 + 50971 = 51042
73 + 50969 = 51042
113 + 50929 = 51042
149 + 50893 = 51042
151 + 50891 = 51042

Showing the first eight; more decompositions exist.
