Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643532, here are decompositions:

5 + 8643527 = 8643532
11 + 8643521 = 8643532
89 + 8643443 = 8643532
173 + 8643359 = 8643532
251 + 8643281 = 8643532
383 + 8643149 = 8643532
389 + 8643143 = 8643532
449 + 8643083 = 8643532

Showing the first eight; more decompositions exist.
