Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490152, here are decompositions:

31 + 490121 = 490152
41 + 490111 = 490152
149 + 490003 = 490152
151 + 490001 = 490152
163 + 489989 = 490152
191 + 489961 = 490152
193 + 489959 = 490152
211 + 489941 = 490152

Showing the first eight; more decompositions exist.
