Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490738, here are decompositions:

5 + 490733 = 490738
41 + 490697 = 490738
107 + 490631 = 490738
167 + 490571 = 490738
179 + 490559 = 490738
197 + 490541 = 490738
239 + 490499 = 490738
257 + 490481 = 490738

Showing the first eight; more decompositions exist.
