Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669726, here are decompositions:

97 + 8669629 = 8669726
103 + 8669623 = 8669726
199 + 8669527 = 8669726
283 + 8669443 = 8669726
337 + 8669389 = 8669726
397 + 8669329 = 8669726
409 + 8669317 = 8669726
433 + 8669293 = 8669726

Showing the first eight; more decompositions exist.
