Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490752, here are decompositions:

11 + 490741 = 490752
19 + 490733 = 490752
89 + 490663 = 490752
109 + 490643 = 490752
173 + 490579 = 490752
179 + 490573 = 490752
181 + 490571 = 490752
193 + 490559 = 490752

Showing the first eight; more decompositions exist.
