Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180116, here are decompositions:

19 + 180097 = 180116
43 + 180073 = 180116
73 + 180043 = 180116
109 + 180007 = 180116
127 + 179989 = 180116
163 + 179953 = 180116
193 + 179923 = 180116
199 + 179917 = 180116

Showing the first eight; more decompositions exist.
