Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490772, here are decompositions:

3 + 490769 = 490772
31 + 490741 = 490772
109 + 490663 = 490772
181 + 490591 = 490772
193 + 490579 = 490772
199 + 490573 = 490772
223 + 490549 = 490772
229 + 490543 = 490772

Showing the first eight; more decompositions exist.
