Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102078, here are decompositions:

7 + 102071 = 102078
17 + 102061 = 102078
19 + 102059 = 102078
47 + 102031 = 102078
59 + 102019 = 102078
79 + 101999 = 102078
101 + 101977 = 102078
139 + 101939 = 102078

Showing the first eight; more decompositions exist.
