Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646402, here are decompositions:

13 + 8646389 = 8646402
41 + 8646361 = 8646402
73 + 8646329 = 8646402
103 + 8646299 = 8646402
109 + 8646293 = 8646402
179 + 8646223 = 8646402
181 + 8646221 = 8646402
239 + 8646163 = 8646402

Showing the first eight; more decompositions exist.
