Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77994, here are decompositions:

11 + 77983 = 77994
17 + 77977 = 77994
43 + 77951 = 77994
61 + 77933 = 77994
101 + 77893 = 77994
127 + 77867 = 77994
131 + 77863 = 77994
181 + 77813 = 77994

Showing the first eight; more decompositions exist.
