Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490156, here are decompositions:

5 + 490151 = 490156
53 + 490103 = 490156
59 + 490097 = 490156
137 + 490019 = 490156
167 + 489989 = 490156
179 + 489977 = 490156
197 + 489959 = 490156
269 + 489887 = 490156

Showing the first eight; more decompositions exist.
