Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162078, here are decompositions:

19 + 162059 = 162078
61 + 162017 = 162078
67 + 162011 = 162078
71 + 162007 = 162078
79 + 161999 = 162078
101 + 161977 = 162078
107 + 161971 = 162078
109 + 161969 = 162078

Showing the first eight; more decompositions exist.
