Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180072, here are decompositions:

19 + 180053 = 180072
29 + 180043 = 180072
71 + 180001 = 180072
73 + 179999 = 180072
83 + 179989 = 180072
103 + 179969 = 180072
149 + 179923 = 180072
163 + 179909 = 180072

Showing the first eight; more decompositions exist.
