Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642506, here are decompositions:

17 + 8642489 = 8642506
53 + 8642453 = 8642506
269 + 8642237 = 8642506
317 + 8642189 = 8642506
347 + 8642159 = 8642506
359 + 8642147 = 8642506
443 + 8642063 = 8642506
449 + 8642057 = 8642506

Showing the first eight; more decompositions exist.
