Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179972, here are decompositions:

3 + 179969 = 179972
19 + 179953 = 179972
73 + 179899 = 179972
139 + 179833 = 179972
151 + 179821 = 179972
193 + 179779 = 179972
223 + 179749 = 179972
229 + 179743 = 179972

Showing the first eight; more decompositions exist.
