Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660828, here are decompositions:

31 + 8660797 = 8660828
61 + 8660767 = 8660828
139 + 8660689 = 8660828
157 + 8660671 = 8660828
367 + 8660461 = 8660828
409 + 8660419 = 8660828
541 + 8660287 = 8660828
601 + 8660227 = 8660828

Showing the first eight; more decompositions exist.
