Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639626, here are decompositions:

29 + 8639597 = 8639626
59 + 8639567 = 8639626
167 + 8639459 = 8639626
173 + 8639453 = 8639626
263 + 8639363 = 8639626
353 + 8639273 = 8639626
419 + 8639207 = 8639626
449 + 8639177 = 8639626

Showing the first eight; more decompositions exist.
