Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492220, here are decompositions:

107 + 492113 = 492220
137 + 492083 = 492220
167 + 492053 = 492220
173 + 492047 = 492220
191 + 492029 = 492220
251 + 491969 = 492220
269 + 491951 = 492220
347 + 491873 = 492220

Showing the first eight; more decompositions exist.
