Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642492, here are decompositions:

3 + 8642489 = 8642492
43 + 8642449 = 8642492
109 + 8642383 = 8642492
163 + 8642329 = 8642492
211 + 8642281 = 8642492
373 + 8642119 = 8642492
433 + 8642059 = 8642492
601 + 8641891 = 8642492

Showing the first eight; more decompositions exist.
