Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179180, here are decompositions:

7 + 179173 = 179180
13 + 179167 = 179180
19 + 179161 = 179180
37 + 179143 = 179180
61 + 179119 = 179180
73 + 179107 = 179180
97 + 179083 = 179180
139 + 179041 = 179180

Showing the first eight; more decompositions exist.
