Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670228, here are decompositions:

31 + 8670197 = 8670228
37 + 8670191 = 8670228
71 + 8670157 = 8670228
101 + 8670127 = 8670228
139 + 8670089 = 8670228
157 + 8670071 = 8670228
191 + 8670037 = 8670228
197 + 8670031 = 8670228

Showing the first eight; more decompositions exist.
