Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660658, here are decompositions:

5 + 8660653 = 8660658
47 + 8660611 = 8660658
79 + 8660579 = 8660658
89 + 8660569 = 8660658
131 + 8660527 = 8660658
151 + 8660507 = 8660658
191 + 8660467 = 8660658
197 + 8660461 = 8660658

Showing the first eight; more decompositions exist.
