Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179220, here are decompositions:

7 + 179213 = 179220
11 + 179209 = 179220
17 + 179203 = 179220
47 + 179173 = 179220
53 + 179167 = 179220
59 + 179161 = 179220
101 + 179119 = 179220
109 + 179111 = 179220

Showing the first eight; more decompositions exist.
