Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670212, here are decompositions:

181 + 8670031 = 8670212
223 + 8669989 = 8670212
283 + 8669929 = 8670212
541 + 8669671 = 8670212
601 + 8669611 = 8670212
619 + 8669593 = 8670212
769 + 8669443 = 8670212
823 + 8669389 = 8670212

Showing the first eight; more decompositions exist.
