Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642354, here are decompositions:

73 + 8642281 = 8642354
157 + 8642197 = 8642354
181 + 8642173 = 8642354
277 + 8642077 = 8642354
367 + 8641987 = 8642354
397 + 8641957 = 8642354
463 + 8641891 = 8642354
547 + 8641807 = 8642354

Showing the first eight; more decompositions exist.
