Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 576820, here are decompositions:

29 + 576791 = 576820
71 + 576749 = 576820
89 + 576731 = 576820
131 + 576689 = 576820
137 + 576683 = 576820
149 + 576671 = 576820
173 + 576647 = 576820
239 + 576581 = 576820

Showing the first eight; more decompositions exist.
