Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501780, here are decompositions:

11 + 501769 = 501780
61 + 501719 = 501780
73 + 501707 = 501780
79 + 501701 = 501780
89 + 501691 = 501780
157 + 501623 = 501780
163 + 501617 = 501780
179 + 501601 = 501780

Showing the first eight; more decompositions exist.
