Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502782, here are decompositions:

11 + 502771 = 502782
13 + 502769 = 502782
53 + 502729 = 502782
79 + 502703 = 502782
83 + 502699 = 502782
113 + 502669 = 502782
131 + 502651 = 502782
139 + 502643 = 502782

Showing the first eight; more decompositions exist.
