Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690870, here are decompositions:

3 + 8690867 = 8690870
43 + 8690827 = 8690870
73 + 8690797 = 8690870
103 + 8690767 = 8690870
157 + 8690713 = 8690870
193 + 8690677 = 8690870
211 + 8690659 = 8690870
271 + 8690599 = 8690870

Showing the first eight; more decompositions exist.
