Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502842, here are decompositions:

13 + 502829 = 502842
23 + 502819 = 502842
61 + 502781 = 502842
71 + 502771 = 502842
73 + 502769 = 502842
113 + 502729 = 502842
139 + 502703 = 502842
173 + 502669 = 502842

Showing the first eight; more decompositions exist.
