Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715742, here are decompositions:

11 + 8715731 = 8715742
23 + 8715719 = 8715742
71 + 8715671 = 8715742
83 + 8715659 = 8715742
89 + 8715653 = 8715742
293 + 8715449 = 8715742
311 + 8715431 = 8715742
359 + 8715383 = 8715742

Showing the first eight; more decompositions exist.
