Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490194, here are decompositions:

11 + 490183 = 490194
43 + 490151 = 490194
73 + 490121 = 490194
83 + 490111 = 490194
97 + 490097 = 490194
137 + 490057 = 490194
163 + 490031 = 490194
191 + 490003 = 490194

Showing the first eight; more decompositions exist.
