Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680064, here are decompositions:

31 + 8680033 = 8680064
37 + 8680027 = 8680064
61 + 8680003 = 8680064
73 + 8679991 = 8680064
181 + 8679883 = 8680064
193 + 8679871 = 8680064
223 + 8679841 = 8680064
457 + 8679607 = 8680064

Showing the first eight; more decompositions exist.
