Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639466, here are decompositions:

5 + 8639461 = 8639466
7 + 8639459 = 8639466
13 + 8639453 = 8639466
23 + 8639443 = 8639466
53 + 8639413 = 8639466
103 + 8639363 = 8639466
167 + 8639299 = 8639466
193 + 8639273 = 8639466

Showing the first eight; more decompositions exist.
