Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77904, here are decompositions:

5 + 77899 = 77904
11 + 77893 = 77904
37 + 77867 = 77904
41 + 77863 = 77904
103 + 77801 = 77904
107 + 77797 = 77904
131 + 77773 = 77904
157 + 77747 = 77904

Showing the first eight; more decompositions exist.
