Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490112, here are decompositions:

79 + 490033 = 490112
109 + 490003 = 490112
151 + 489961 = 490112
199 + 489913 = 490112
211 + 489901 = 490112
241 + 489871 = 490112
313 + 489799 = 490112
379 + 489733 = 490112

Showing the first eight; more decompositions exist.
