Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492042, here are decompositions:

13 + 492029 = 492042
29 + 492013 = 492042
59 + 491983 = 492042
73 + 491969 = 492042
191 + 491851 = 492042
223 + 491819 = 492042
269 + 491773 = 492042
311 + 491731 = 492042

Showing the first eight; more decompositions exist.
