Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751822, here are decompositions:

5 + 8751817 = 8751822
19 + 8751803 = 8751822
41 + 8751781 = 8751822
73 + 8751749 = 8751822
83 + 8751739 = 8751822
89 + 8751733 = 8751822
151 + 8751671 = 8751822
193 + 8751629 = 8751822

Showing the first eight; more decompositions exist.
