Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680870, here are decompositions:

47 + 8680823 = 8680870
59 + 8680811 = 8680870
89 + 8680781 = 8680870
101 + 8680769 = 8680870
137 + 8680733 = 8680870
173 + 8680697 = 8680870
179 + 8680691 = 8680870
239 + 8680631 = 8680870

Showing the first eight; more decompositions exist.
