Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490364, here are decompositions:

97 + 490267 = 490364
157 + 490207 = 490364
163 + 490201 = 490364
181 + 490183 = 490364
307 + 490057 = 490364
331 + 490033 = 490364
421 + 489943 = 490364
463 + 489901 = 490364

Showing the first eight; more decompositions exist.
