Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669426, here are decompositions:

37 + 8669389 = 8669426
97 + 8669329 = 8669426
109 + 8669317 = 8669426
193 + 8669233 = 8669426
313 + 8669113 = 8669426
433 + 8668993 = 8669426
613 + 8668813 = 8669426
643 + 8668783 = 8669426

Showing the first eight; more decompositions exist.
