Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745940, here are decompositions:

11 + 8745929 = 8745940
17 + 8745923 = 8745940
23 + 8745917 = 8745940
59 + 8745881 = 8745940
83 + 8745857 = 8745940
113 + 8745827 = 8745940
173 + 8745767 = 8745940
191 + 8745749 = 8745940

Showing the first eight; more decompositions exist.
