Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77898, here are decompositions:

5 + 77893 = 77898
31 + 77867 = 77898
59 + 77839 = 77898
97 + 77801 = 77898
101 + 77797 = 77898
137 + 77761 = 77898
151 + 77747 = 77898
167 + 77731 = 77898

Showing the first eight; more decompositions exist.
