Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51078, here are decompositions:

7 + 51071 = 51078
17 + 51061 = 51078
19 + 51059 = 51078
31 + 51047 = 51078
47 + 51031 = 51078
89 + 50989 = 51078
107 + 50971 = 51078
109 + 50969 = 51078

Showing the first eight; more decompositions exist.
