Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490142, here are decompositions:

31 + 490111 = 490142
109 + 490033 = 490142
139 + 490003 = 490142
181 + 489961 = 490142
199 + 489943 = 490142
229 + 489913 = 490142
241 + 489901 = 490142
271 + 489871 = 490142

Showing the first eight; more decompositions exist.
