Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669738, here are decompositions:

37 + 8669701 = 8669738
67 + 8669671 = 8669738
109 + 8669629 = 8669738
127 + 8669611 = 8669738
211 + 8669527 = 8669738
349 + 8669389 = 8669738
397 + 8669341 = 8669738
409 + 8669329 = 8669738

Showing the first eight; more decompositions exist.
