Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942180, here are decompositions:

11 + 942169 = 942180
13 + 942167 = 942180
17 + 942163 = 942180
37 + 942143 = 942180
67 + 942113 = 942180
79 + 942101 = 942180
89 + 942091 = 942180
101 + 942079 = 942180

Showing the first eight; more decompositions exist.
