Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643462, here are decompositions:

5 + 8643457 = 8643462
19 + 8643443 = 8643462
29 + 8643433 = 8643462
53 + 8643409 = 8643462
103 + 8643359 = 8643462
181 + 8643281 = 8643462
239 + 8643223 = 8643462
251 + 8643211 = 8643462

Showing the first eight; more decompositions exist.
