Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643802, here are decompositions:

5 + 8643797 = 8643802
23 + 8643779 = 8643802
53 + 8643749 = 8643802
131 + 8643671 = 8643802
239 + 8643563 = 8643802
263 + 8643539 = 8643802
281 + 8643521 = 8643802
359 + 8643443 = 8643802

Showing the first eight; more decompositions exist.
