Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731824, here are decompositions:

5 + 8731819 = 8731824
7 + 8731817 = 8731824
37 + 8731787 = 8731824
41 + 8731783 = 8731824
47 + 8731777 = 8731824
61 + 8731763 = 8731824
67 + 8731757 = 8731824
103 + 8731721 = 8731824

Showing the first eight; more decompositions exist.
