Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77892, here are decompositions:

29 + 77863 = 77892
43 + 77849 = 77892
53 + 77839 = 77892
79 + 77813 = 77892
109 + 77783 = 77892
131 + 77761 = 77892
149 + 77743 = 77892
173 + 77719 = 77892

Showing the first eight; more decompositions exist.
