Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669740, here are decompositions:

71 + 8669669 = 8669740
83 + 8669657 = 8669740
89 + 8669651 = 8669740
113 + 8669627 = 8669740
197 + 8669543 = 8669740
227 + 8669513 = 8669740
239 + 8669501 = 8669740
251 + 8669489 = 8669740

Showing the first eight; more decompositions exist.
