Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643472, here are decompositions:

29 + 8643443 = 8643472
113 + 8643359 = 8643472
191 + 8643281 = 8643472
263 + 8643209 = 8643472
389 + 8643083 = 8643472
419 + 8643053 = 8643472
449 + 8643023 = 8643472
521 + 8642951 = 8643472

Showing the first eight; more decompositions exist.
