Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180126, here are decompositions:

29 + 180097 = 180126
53 + 180073 = 180126
73 + 180053 = 180126
83 + 180043 = 180126
103 + 180023 = 180126
127 + 179999 = 180126
137 + 179989 = 180126
157 + 179969 = 180126

Showing the first eight; more decompositions exist.
