Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646394, here are decompositions:

5 + 8646389 = 8646394
17 + 8646377 = 8646394
101 + 8646293 = 8646394
137 + 8646257 = 8646394
167 + 8646227 = 8646394
173 + 8646221 = 8646394
467 + 8645927 = 8646394
761 + 8645633 = 8646394

Showing the first eight; more decompositions exist.
