Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180106, here are decompositions:

29 + 180077 = 180106
53 + 180053 = 180106
83 + 180023 = 180106
107 + 179999 = 180106
137 + 179969 = 180106
149 + 179957 = 180106
167 + 179939 = 180106
197 + 179909 = 180106

Showing the first eight; more decompositions exist.
