Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727940, here are decompositions:

3 + 8727937 = 8727940
41 + 8727899 = 8727940
83 + 8727857 = 8727940
131 + 8727809 = 8727940
149 + 8727791 = 8727940
167 + 8727773 = 8727940
173 + 8727767 = 8727940
239 + 8727701 = 8727940

Showing the first eight; more decompositions exist.
