Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633742, here are decompositions:

11 + 8633731 = 8633742
23 + 8633719 = 8633742
31 + 8633711 = 8633742
41 + 8633701 = 8633742
43 + 8633699 = 8633742
59 + 8633683 = 8633742
79 + 8633663 = 8633742
83 + 8633659 = 8633742

Showing the first eight; more decompositions exist.
