Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632840, here are decompositions:

11 + 8632829 = 8632840
23 + 8632817 = 8632840
113 + 8632727 = 8632840
173 + 8632667 = 8632840
179 + 8632661 = 8632840
191 + 8632649 = 8632840
311 + 8632529 = 8632840
317 + 8632523 = 8632840

Showing the first eight; more decompositions exist.
