Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751666, here are decompositions:

37 + 8751629 = 8751666
47 + 8751619 = 8751666
67 + 8751599 = 8751666
73 + 8751593 = 8751666
89 + 8751577 = 8751666
103 + 8751563 = 8751666
109 + 8751557 = 8751666
139 + 8751527 = 8751666

Showing the first eight; more decompositions exist.
