Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643542, here are decompositions:

3 + 8643539 = 8643542
109 + 8643433 = 8643542
199 + 8643343 = 8643542
331 + 8643211 = 8643542
409 + 8643133 = 8643542
421 + 8643121 = 8643542
433 + 8643109 = 8643542
631 + 8642911 = 8643542

Showing the first eight; more decompositions exist.
