Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680100, here are decompositions:

67 + 8680033 = 8680100
73 + 8680027 = 8680100
97 + 8680003 = 8680100
109 + 8679991 = 8680100
127 + 8679973 = 8680100
157 + 8679943 = 8680100
229 + 8679871 = 8680100
571 + 8679529 = 8680100

Showing the first eight; more decompositions exist.
