Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180798, here are decompositions:

5 + 180793 = 180798
19 + 180779 = 180798
47 + 180751 = 180798
67 + 180731 = 180798
97 + 180701 = 180798
131 + 180667 = 180798
151 + 180647 = 180798
181 + 180617 = 180798

Showing the first eight; more decompositions exist.
