Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492140, here are decompositions:

37 + 492103 = 492140
73 + 492067 = 492140
79 + 492061 = 492140
127 + 492013 = 492140
157 + 491983 = 492140
163 + 491977 = 492140
241 + 491899 = 492140
283 + 491857 = 492140

Showing the first eight; more decompositions exist.
