Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646690, here are decompositions:

7 + 8646683 = 8646690
23 + 8646667 = 8646690
83 + 8646607 = 8646690
109 + 8646581 = 8646690
131 + 8646559 = 8646690
179 + 8646511 = 8646690
193 + 8646497 = 8646690
211 + 8646479 = 8646690

Showing the first eight; more decompositions exist.
