Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643262, here are decompositions:

53 + 8643209 = 8643262
113 + 8643149 = 8643262
179 + 8643083 = 8643262
239 + 8643023 = 8643262
311 + 8642951 = 8643262
359 + 8642903 = 8643262
401 + 8642861 = 8643262
443 + 8642819 = 8643262

Showing the first eight; more decompositions exist.
