Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666042, here are decompositions:

19 + 8666023 = 8666042
43 + 8665999 = 8666042
103 + 8665939 = 8666042
109 + 8665933 = 8666042
193 + 8665849 = 8666042
409 + 8665633 = 8666042
439 + 8665603 = 8666042
499 + 8665543 = 8666042

Showing the first eight; more decompositions exist.
