Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741980, here are decompositions:

3 + 8741977 = 8741980
29 + 8741951 = 8741980
47 + 8741933 = 8741980
113 + 8741867 = 8741980
167 + 8741813 = 8741980
179 + 8741801 = 8741980
227 + 8741753 = 8741980
239 + 8741741 = 8741980

Showing the first eight; more decompositions exist.
