Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642892, here are decompositions:

29 + 8642863 = 8642892
31 + 8642861 = 8642892
43 + 8642849 = 8642892
53 + 8642839 = 8642892
73 + 8642819 = 8642892
131 + 8642761 = 8642892
241 + 8642651 = 8642892
311 + 8642581 = 8642892

Showing the first eight; more decompositions exist.
