Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648870, here are decompositions:

3 + 8648867 = 8648870
7 + 8648863 = 8648870
31 + 8648839 = 8648870
37 + 8648833 = 8648870
73 + 8648797 = 8648870
79 + 8648791 = 8648870
193 + 8648677 = 8648870
313 + 8648557 = 8648870

Showing the first eight; more decompositions exist.
