Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642862, here are decompositions:

5 + 8642857 = 8642862
13 + 8642849 = 8642862
23 + 8642839 = 8642862
43 + 8642819 = 8642862
89 + 8642773 = 8642862
101 + 8642761 = 8642862
139 + 8642723 = 8642862
211 + 8642651 = 8642862

Showing the first eight; more decompositions exist.
