Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642802, here are decompositions:

29 + 8642773 = 8642802
41 + 8642761 = 8642802
79 + 8642723 = 8642802
151 + 8642651 = 8642802
211 + 8642591 = 8642802
269 + 8642533 = 8642802
283 + 8642519 = 8642802
293 + 8642509 = 8642802

Showing the first eight; more decompositions exist.
