Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642406, here are decompositions:

23 + 8642383 = 8642406
103 + 8642303 = 8642406
233 + 8642173 = 8642406
307 + 8642099 = 8642406
347 + 8642059 = 8642406
349 + 8642057 = 8642406
373 + 8642033 = 8642406
379 + 8642027 = 8642406

Showing the first eight; more decompositions exist.
