Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77854, here are decompositions:

5 + 77849 = 77854
41 + 77813 = 77854
53 + 77801 = 77854
71 + 77783 = 77854
107 + 77747 = 77854
131 + 77723 = 77854
167 + 77687 = 77854
173 + 77681 = 77854

Showing the first eight; more decompositions exist.
