Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468820, here are decompositions:

3 + 468817 = 468820
17 + 468803 = 468820
47 + 468773 = 468820
59 + 468761 = 468820
83 + 468737 = 468820
101 + 468719 = 468820
137 + 468683 = 468820
167 + 468653 = 468820

Showing the first eight; more decompositions exist.
