Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77988, here are decompositions:

5 + 77983 = 77988
11 + 77977 = 77988
19 + 77969 = 77988
37 + 77951 = 77988
59 + 77929 = 77988
89 + 77899 = 77988
139 + 77849 = 77988
149 + 77839 = 77988

Showing the first eight; more decompositions exist.
