Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705090, here are decompositions:

3 + 8705087 = 8705090
13 + 8705077 = 8705090
61 + 8705029 = 8705090
109 + 8704981 = 8705090
139 + 8704951 = 8705090
181 + 8704909 = 8705090
193 + 8704897 = 8705090
307 + 8704783 = 8705090

Showing the first eight; more decompositions exist.
