Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707664, here are decompositions:

3 + 8707661 = 8707664
13 + 8707651 = 8707664
61 + 8707603 = 8707664
73 + 8707591 = 8707664
127 + 8707537 = 8707664
271 + 8707393 = 8707664
307 + 8707357 = 8707664
313 + 8707351 = 8707664

Showing the first eight; more decompositions exist.
