Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700212, here are decompositions:

19 + 8700193 = 8700212
43 + 8700169 = 8700212
181 + 8700031 = 8700212
193 + 8700019 = 8700212
211 + 8700001 = 8700212
571 + 8699641 = 8700212
601 + 8699611 = 8700212
673 + 8699539 = 8700212

Showing the first eight; more decompositions exist.
