Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673664, here are decompositions:

53 + 8673611 = 8673664
71 + 8673593 = 8673664
317 + 8673347 = 8673664
443 + 8673221 = 8673664
557 + 8673107 = 8673664
653 + 8673011 = 8673664
773 + 8672891 = 8673664
863 + 8672801 = 8673664

Showing the first eight; more decompositions exist.
