Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492180, here are decompositions:

67 + 492113 = 492180
97 + 492083 = 492180
103 + 492077 = 492180
113 + 492067 = 492180
127 + 492053 = 492180
151 + 492029 = 492180
163 + 492017 = 492180
167 + 492013 = 492180

Showing the first eight; more decompositions exist.
