Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740818, here are decompositions:

11 + 8740807 = 8740818
19 + 8740799 = 8740818
29 + 8740789 = 8740818
61 + 8740757 = 8740818
137 + 8740681 = 8740818
139 + 8740679 = 8740818
211 + 8740607 = 8740818
227 + 8740591 = 8740818

Showing the first eight; more decompositions exist.
