Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490140, here are decompositions:

19 + 490121 = 490140
23 + 490117 = 490140
29 + 490111 = 490140
37 + 490103 = 490140
43 + 490097 = 490140
83 + 490057 = 490140
107 + 490033 = 490140
109 + 490031 = 490140

Showing the first eight; more decompositions exist.
