Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639746, here are decompositions:

83 + 8639663 = 8639746
107 + 8639639 = 8639746
149 + 8639597 = 8639746
179 + 8639567 = 8639746
197 + 8639549 = 8639746
239 + 8639507 = 8639746
293 + 8639453 = 8639746
383 + 8639363 = 8639746

Showing the first eight; more decompositions exist.
