Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502780, here are decompositions:

11 + 502769 = 502780
137 + 502643 = 502780
149 + 502631 = 502780
167 + 502613 = 502780
227 + 502553 = 502780
263 + 502517 = 502780
281 + 502499 = 502780
293 + 502487 = 502780

Showing the first eight; more decompositions exist.
