Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680142, here are decompositions:

43 + 8680099 = 8680142
109 + 8680033 = 8680142
139 + 8680003 = 8680142
151 + 8679991 = 8680142
199 + 8679943 = 8680142
271 + 8679871 = 8680142
433 + 8679709 = 8680142
613 + 8679529 = 8680142

Showing the first eight; more decompositions exist.
