Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669818, here are decompositions:

41 + 8669777 = 8669818
149 + 8669669 = 8669818
167 + 8669651 = 8669818
191 + 8669627 = 8669818
197 + 8669621 = 8669818
317 + 8669501 = 8669818
401 + 8669417 = 8669818
419 + 8669399 = 8669818

Showing the first eight; more decompositions exist.
