Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670158, here are decompositions:

31 + 8670127 = 8670158
127 + 8670031 = 8670158
151 + 8670007 = 8670158
229 + 8669929 = 8670158
337 + 8669821 = 8670158
457 + 8669701 = 8670158
487 + 8669671 = 8670158
547 + 8669611 = 8670158

Showing the first eight; more decompositions exist.
