Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500810, here are decompositions:

3 + 500807 = 500810
19 + 500791 = 500810
97 + 500713 = 500810
139 + 500671 = 500810
181 + 500629 = 500810
223 + 500587 = 500810
283 + 500527 = 500810
337 + 500473 = 500810

Showing the first eight; more decompositions exist.
