Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731884, here are decompositions:

11 + 8731873 = 8731884
17 + 8731867 = 8731884
23 + 8731861 = 8731884
53 + 8731831 = 8731884
67 + 8731817 = 8731884
97 + 8731787 = 8731884
101 + 8731783 = 8731884
107 + 8731777 = 8731884

Showing the first eight; more decompositions exist.
