Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669858, here are decompositions:

37 + 8669821 = 8669858
157 + 8669701 = 8669858
229 + 8669629 = 8669858
331 + 8669527 = 8669858
541 + 8669317 = 8669858
607 + 8669251 = 8669858
619 + 8669239 = 8669858
751 + 8669107 = 8669858

Showing the first eight; more decompositions exist.
