Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102836, here are decompositions:

7 + 102829 = 102836
43 + 102793 = 102836
67 + 102769 = 102836
73 + 102763 = 102836
157 + 102679 = 102836
163 + 102673 = 102836
193 + 102643 = 102836
229 + 102607 = 102836

Showing the first eight; more decompositions exist.
