Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490120, here are decompositions:

3 + 490117 = 490120
17 + 490103 = 490120
23 + 490097 = 490120
89 + 490031 = 490120
101 + 490019 = 490120
131 + 489989 = 490120
179 + 489941 = 490120
233 + 489887 = 490120

Showing the first eight; more decompositions exist.
