Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492154, here are decompositions:

41 + 492113 = 492154
71 + 492083 = 492154
101 + 492053 = 492154
107 + 492047 = 492154
137 + 492017 = 492154
281 + 491873 = 492154
317 + 491837 = 492154
503 + 491651 = 492154

Showing the first eight; more decompositions exist.
