Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670428, here are decompositions:

31 + 8670397 = 8670428
97 + 8670331 = 8670428
127 + 8670301 = 8670428
271 + 8670157 = 8670428
397 + 8670031 = 8670428
421 + 8670007 = 8670428
439 + 8669989 = 8670428
499 + 8669929 = 8670428

Showing the first eight; more decompositions exist.
