Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643476, here are decompositions:

19 + 8643457 = 8643476
43 + 8643433 = 8643476
67 + 8643409 = 8643476
109 + 8643367 = 8643476
139 + 8643337 = 8643476
277 + 8643199 = 8643476
367 + 8643109 = 8643476
463 + 8643013 = 8643476

Showing the first eight; more decompositions exist.
