Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643762, here are decompositions:

5 + 8643757 = 8643762
13 + 8643749 = 8643762
41 + 8643721 = 8643762
89 + 8643673 = 8643762
131 + 8643631 = 8643762
173 + 8643589 = 8643762
199 + 8643563 = 8643762
223 + 8643539 = 8643762

Showing the first eight; more decompositions exist.
