Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670128, here are decompositions:

97 + 8670031 = 8670128
139 + 8669989 = 8670128
199 + 8669929 = 8670128
307 + 8669821 = 8670128
457 + 8669671 = 8670128
499 + 8669629 = 8670128
601 + 8669527 = 8670128
739 + 8669389 = 8670128

Showing the first eight; more decompositions exist.
