Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659880, here are decompositions:

7 + 8659873 = 8659880
13 + 8659867 = 8659880
43 + 8659837 = 8659880
139 + 8659741 = 8659880
211 + 8659669 = 8659880
337 + 8659543 = 8659880
349 + 8659531 = 8659880
367 + 8659513 = 8659880

Showing the first eight; more decompositions exist.
