Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648542, here are decompositions:

5 + 8648537 = 8648542
11 + 8648531 = 8648542
29 + 8648513 = 8648542
41 + 8648501 = 8648542
83 + 8648459 = 8648542
173 + 8648369 = 8648542
431 + 8648111 = 8648542
443 + 8648099 = 8648542

Showing the first eight; more decompositions exist.
