Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751824, here are decompositions:

7 + 8751817 = 8751824
43 + 8751781 = 8751824
97 + 8751727 = 8751824
157 + 8751667 = 8751824
331 + 8751493 = 8751824
373 + 8751451 = 8751824
397 + 8751427 = 8751824
457 + 8751367 = 8751824

Showing the first eight; more decompositions exist.
