Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680158, here are decompositions:

5 + 8680153 = 8680158
37 + 8680121 = 8680158
59 + 8680099 = 8680158
131 + 8680027 = 8680158
167 + 8679991 = 8680158
271 + 8679887 = 8680158
317 + 8679841 = 8680158
367 + 8679791 = 8680158

Showing the first eight; more decompositions exist.
