Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642624, here are decompositions:

43 + 8642581 = 8642624
157 + 8642467 = 8642624
241 + 8642383 = 8642624
547 + 8642077 = 8642624
733 + 8641891 = 8642624
751 + 8641873 = 8642624
877 + 8641747 = 8642624
883 + 8641741 = 8642624

Showing the first eight; more decompositions exist.
