Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751738, here are decompositions:

5 + 8751733 = 8751738
11 + 8751727 = 8751738
67 + 8751671 = 8751738
71 + 8751667 = 8751738
109 + 8751629 = 8751738
139 + 8751599 = 8751738
181 + 8751557 = 8751738
211 + 8751527 = 8751738

Showing the first eight; more decompositions exist.
