Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492012, here are decompositions:

5 + 492007 = 492012
29 + 491983 = 492012
43 + 491969 = 492012
61 + 491951 = 492012
89 + 491923 = 492012
113 + 491899 = 492012
139 + 491873 = 492012
179 + 491833 = 492012

Showing the first eight; more decompositions exist.
