Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731984, here are decompositions:

3 + 8731981 = 8731984
5 + 8731979 = 8731984
47 + 8731937 = 8731984
71 + 8731913 = 8731984
83 + 8731901 = 8731984
167 + 8731817 = 8731984
197 + 8731787 = 8731984
227 + 8731757 = 8731984

Showing the first eight; more decompositions exist.
