Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670080, here are decompositions:

43 + 8670037 = 8670080
73 + 8670007 = 8670080
151 + 8669929 = 8670080
157 + 8669923 = 8670080
313 + 8669767 = 8670080
379 + 8669701 = 8670080
409 + 8669671 = 8670080
457 + 8669623 = 8670080

Showing the first eight; more decompositions exist.
