Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751836, here are decompositions:

7 + 8751829 = 8751836
19 + 8751817 = 8751836
97 + 8751739 = 8751836
103 + 8751733 = 8751836
109 + 8751727 = 8751836
367 + 8751469 = 8751836
397 + 8751439 = 8751836
409 + 8751427 = 8751836

Showing the first eight; more decompositions exist.
