Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666602, here are decompositions:

5 + 8666597 = 8666602
11 + 8666591 = 8666602
59 + 8666543 = 8666602
83 + 8666519 = 8666602
89 + 8666513 = 8666602
101 + 8666501 = 8666602
233 + 8666369 = 8666602
251 + 8666351 = 8666602

Showing the first eight; more decompositions exist.
