Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643612, here are decompositions:

23 + 8643589 = 8643612
73 + 8643539 = 8643612
179 + 8643433 = 8643612
269 + 8643343 = 8643612
331 + 8643281 = 8643612
389 + 8643223 = 8643612
401 + 8643211 = 8643612
431 + 8643181 = 8643612

Showing the first eight; more decompositions exist.
