Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680042, here are decompositions:

5 + 8680037 = 8680042
71 + 8679971 = 8680042
89 + 8679953 = 8680042
251 + 8679791 = 8680042
401 + 8679641 = 8680042
461 + 8679581 = 8680042
491 + 8679551 = 8680042
593 + 8679449 = 8680042

Showing the first eight; more decompositions exist.
