Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660478, here are decompositions:

11 + 8660467 = 8660478
17 + 8660461 = 8660478
41 + 8660437 = 8660478
59 + 8660419 = 8660478
97 + 8660381 = 8660478
109 + 8660369 = 8660478
139 + 8660339 = 8660478
181 + 8660297 = 8660478

Showing the first eight; more decompositions exist.
