Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750772, here are decompositions:

11 + 8750761 = 8750772
53 + 8750719 = 8750772
59 + 8750713 = 8750772
71 + 8750701 = 8750772
83 + 8750689 = 8750772
131 + 8750641 = 8750772
181 + 8750591 = 8750772
223 + 8750549 = 8750772

Showing the first eight; more decompositions exist.
