Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666048, here are decompositions:

31 + 8666017 = 8666048
109 + 8665939 = 8666048
151 + 8665897 = 8666048
199 + 8665849 = 8666048
271 + 8665777 = 8666048
331 + 8665717 = 8666048
397 + 8665651 = 8666048
487 + 8665561 = 8666048

Showing the first eight; more decompositions exist.
