Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743722, here are decompositions:

5 + 8743717 = 8743722
11 + 8743711 = 8743722
41 + 8743681 = 8743722
83 + 8743639 = 8743722
89 + 8743633 = 8743722
101 + 8743621 = 8743722
139 + 8743583 = 8743722
151 + 8743571 = 8743722

Showing the first eight; more decompositions exist.
