Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80180, here are decompositions:

3 + 80177 = 80180
7 + 80173 = 80180
13 + 80167 = 80180
31 + 80149 = 80180
73 + 80107 = 80180
103 + 80077 = 80180
109 + 80071 = 80180
181 + 79999 = 80180

Showing the first eight; more decompositions exist.
