Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666258, here are decompositions:

199 + 8666059 = 8666258
241 + 8666017 = 8666258
409 + 8665849 = 8666258
541 + 8665717 = 8666258
607 + 8665651 = 8666258
691 + 8665567 = 8666258
787 + 8665471 = 8666258
829 + 8665429 = 8666258

Showing the first eight; more decompositions exist.
