Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490496, here are decompositions:

3 + 490493 = 490496
37 + 490459 = 490496
43 + 490453 = 490496
79 + 490417 = 490496
103 + 490393 = 490496
157 + 490339 = 490496
229 + 490267 = 490496
313 + 490183 = 490496

Showing the first eight; more decompositions exist.
