Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750778, here are decompositions:

7 + 8750771 = 8750778
17 + 8750761 = 8750778
41 + 8750737 = 8750778
59 + 8750719 = 8750778
89 + 8750689 = 8750778
137 + 8750641 = 8750778
139 + 8750639 = 8750778
227 + 8750551 = 8750778

Showing the first eight; more decompositions exist.
