Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642394, here are decompositions:

11 + 8642383 = 8642394
113 + 8642281 = 8642394
157 + 8642237 = 8642394
197 + 8642197 = 8642394
283 + 8642111 = 8642394
317 + 8642077 = 8642394
331 + 8642063 = 8642394
337 + 8642057 = 8642394

Showing the first eight; more decompositions exist.
