Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740668, here are decompositions:

11 + 8740657 = 8740668
19 + 8740649 = 8740668
61 + 8740607 = 8740668
89 + 8740579 = 8740668
107 + 8740561 = 8740668
109 + 8740559 = 8740668
127 + 8740541 = 8740668
137 + 8740531 = 8740668

Showing the first eight; more decompositions exist.
