Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490700, here are decompositions:

3 + 490697 = 490700
37 + 490663 = 490700
73 + 490627 = 490700
109 + 490591 = 490700
127 + 490573 = 490700
151 + 490549 = 490700
157 + 490543 = 490700
163 + 490537 = 490700

Showing the first eight; more decompositions exist.
