Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77028, here are decompositions:

5 + 77023 = 77028
11 + 77017 = 77028
37 + 76991 = 77028
67 + 76961 = 77028
79 + 76949 = 77028
109 + 76919 = 77028
157 + 76871 = 77028
181 + 76847 = 77028

Showing the first eight; more decompositions exist.
