Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642458, here are decompositions:

5 + 8642453 = 8642458
29 + 8642429 = 8642458
269 + 8642189 = 8642458
311 + 8642147 = 8642458
317 + 8642141 = 8642458
347 + 8642111 = 8642458
359 + 8642099 = 8642458
401 + 8642057 = 8642458

Showing the first eight; more decompositions exist.
