Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642456, here are decompositions:

3 + 8642453 = 8642456
7 + 8642449 = 8642456
73 + 8642383 = 8642456
127 + 8642329 = 8642456
283 + 8642173 = 8642456
337 + 8642119 = 8642456
349 + 8642107 = 8642456
379 + 8642077 = 8642456

Showing the first eight; more decompositions exist.
