Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642494, here are decompositions:

5 + 8642489 = 8642494
41 + 8642453 = 8642494
191 + 8642303 = 8642494
257 + 8642237 = 8642494
347 + 8642147 = 8642494
353 + 8642141 = 8642494
383 + 8642111 = 8642494
431 + 8642063 = 8642494

Showing the first eight; more decompositions exist.
