Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179838, here are decompositions:

5 + 179833 = 179838
11 + 179827 = 179838
17 + 179821 = 179838
19 + 179819 = 179838
31 + 179807 = 179838
37 + 179801 = 179838
59 + 179779 = 179838
89 + 179749 = 179838

Showing the first eight; more decompositions exist.
