Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670990, here are decompositions:

43 + 8670947 = 8670990
47 + 8670943 = 8670990
71 + 8670919 = 8670990
103 + 8670887 = 8670990
127 + 8670863 = 8670990
179 + 8670811 = 8670990
199 + 8670791 = 8670990
239 + 8670751 = 8670990

Showing the first eight; more decompositions exist.
