Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632842, here are decompositions:

11 + 8632831 = 8632842
13 + 8632829 = 8632842
41 + 8632801 = 8632842
83 + 8632759 = 8632842
181 + 8632661 = 8632842
193 + 8632649 = 8632842
233 + 8632609 = 8632842
263 + 8632579 = 8632842

Showing the first eight; more decompositions exist.
