Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751840, here are decompositions:

11 + 8751829 = 8751840
23 + 8751817 = 8751840
37 + 8751803 = 8751840
59 + 8751781 = 8751840
67 + 8751773 = 8751840
73 + 8751767 = 8751840
101 + 8751739 = 8751840
107 + 8751733 = 8751840

Showing the first eight; more decompositions exist.
