Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77886, here are decompositions:

19 + 77867 = 77886
23 + 77863 = 77886
37 + 77849 = 77886
47 + 77839 = 77886
73 + 77813 = 77886
89 + 77797 = 77886
103 + 77783 = 77886
113 + 77773 = 77886

Showing the first eight; more decompositions exist.
