Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712738, here are decompositions:

11 + 8712727 = 8712738
29 + 8712709 = 8712738
37 + 8712701 = 8712738
61 + 8712677 = 8712738
109 + 8712629 = 8712738
127 + 8712611 = 8712738
137 + 8712601 = 8712738
191 + 8712547 = 8712738

Showing the first eight; more decompositions exist.
