Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643526, here are decompositions:

5 + 8643521 = 8643526
83 + 8643443 = 8643526
167 + 8643359 = 8643526
239 + 8643287 = 8643526
317 + 8643209 = 8643526
383 + 8643143 = 8643526
389 + 8643137 = 8643526
443 + 8643083 = 8643526

Showing the first eight; more decompositions exist.
