Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670180, here are decompositions:

23 + 8670157 = 8670180
53 + 8670127 = 8670180
73 + 8670107 = 8670180
109 + 8670071 = 8670180
139 + 8670041 = 8670180
149 + 8670031 = 8670180
151 + 8670029 = 8670180
173 + 8670007 = 8670180

Showing the first eight; more decompositions exist.
