Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680372, here are decompositions:

3 + 8680369 = 8680372
59 + 8680313 = 8680372
251 + 8680121 = 8680372
269 + 8680103 = 8680372
401 + 8679971 = 8680372
419 + 8679953 = 8680372
821 + 8679551 = 8680372
1019 + 8679353 = 8680372

Showing the first eight; more decompositions exist.
