Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492142, here are decompositions:

29 + 492113 = 492142
59 + 492083 = 492142
83 + 492059 = 492142
89 + 492053 = 492142
113 + 492029 = 492142
173 + 491969 = 492142
191 + 491951 = 492142
269 + 491873 = 492142

Showing the first eight; more decompositions exist.
