Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670064, here are decompositions:

23 + 8670041 = 8670064
71 + 8669993 = 8670064
83 + 8669981 = 8670064
101 + 8669963 = 8670064
167 + 8669897 = 8670064
233 + 8669831 = 8670064
443 + 8669621 = 8670064
521 + 8669543 = 8670064

Showing the first eight; more decompositions exist.
