Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639554, here are decompositions:

3 + 8639551 = 8639554
5 + 8639549 = 8639554
23 + 8639531 = 8639554
47 + 8639507 = 8639554
101 + 8639453 = 8639554
113 + 8639441 = 8639554
173 + 8639381 = 8639554
191 + 8639363 = 8639554

Showing the first eight; more decompositions exist.
