Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670890, here are decompositions:

3 + 8670887 = 8670890
79 + 8670811 = 8670890
139 + 8670751 = 8670890
181 + 8670709 = 8670890
211 + 8670679 = 8670890
223 + 8670667 = 8670890
271 + 8670619 = 8670890
307 + 8670583 = 8670890

Showing the first eight; more decompositions exist.
