Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675664, here are decompositions:

13 + 8675651 = 8675664
43 + 8675621 = 8675664
73 + 8675591 = 8675664
191 + 8675473 = 8675664
223 + 8675441 = 8675664
251 + 8675413 = 8675664
281 + 8675383 = 8675664
293 + 8675371 = 8675664

Showing the first eight; more decompositions exist.
