Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643772, here are decompositions:

23 + 8643749 = 8643772
101 + 8643671 = 8643772
233 + 8643539 = 8643772
251 + 8643521 = 8643772
491 + 8643281 = 8643772
563 + 8643209 = 8643772
719 + 8643053 = 8643772
821 + 8642951 = 8643772

Showing the first eight; more decompositions exist.
