Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502840, here are decompositions:

11 + 502829 = 502840
53 + 502787 = 502840
59 + 502781 = 502840
71 + 502769 = 502840
137 + 502703 = 502840
197 + 502643 = 502840
227 + 502613 = 502840
353 + 502487 = 502840

Showing the first eight; more decompositions exist.
