Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642554, here are decompositions:

47 + 8642507 = 8642554
101 + 8642453 = 8642554
251 + 8642303 = 8642554
317 + 8642237 = 8642554
443 + 8642111 = 8642554
491 + 8642063 = 8642554
521 + 8642033 = 8642554
563 + 8641991 = 8642554

Showing the first eight; more decompositions exist.
