Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492186, here are decompositions:

73 + 492113 = 492186
83 + 492103 = 492186
103 + 492083 = 492186
109 + 492077 = 492186
127 + 492059 = 492186
139 + 492047 = 492186
157 + 492029 = 492186
173 + 492013 = 492186

Showing the first eight; more decompositions exist.
