Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643674, here are decompositions:

3 + 8643671 = 8643674
43 + 8643631 = 8643674
97 + 8643577 = 8643674
241 + 8643433 = 8643674
307 + 8643367 = 8643674
331 + 8643343 = 8643674
337 + 8643337 = 8643674
367 + 8643307 = 8643674

Showing the first eight; more decompositions exist.
