Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675870, here are decompositions:

13 + 8675857 = 8675870
31 + 8675839 = 8675870
37 + 8675833 = 8675870
103 + 8675767 = 8675870
127 + 8675743 = 8675870
193 + 8675677 = 8675870
199 + 8675671 = 8675870
349 + 8675521 = 8675870

Showing the first eight; more decompositions exist.
