Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77998, here are decompositions:

29 + 77969 = 77998
47 + 77951 = 77998
131 + 77867 = 77998
149 + 77849 = 77998
197 + 77801 = 77998
251 + 77747 = 77998
311 + 77687 = 77998
317 + 77681 = 77998

Showing the first eight; more decompositions exist.
