Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622986, here are decompositions:

3 + 8622983 = 8622986
13 + 8622973 = 8622986
103 + 8622883 = 8622986
109 + 8622877 = 8622986
139 + 8622847 = 8622986
193 + 8622793 = 8622986
223 + 8622763 = 8622986
409 + 8622577 = 8622986

Showing the first eight; more decompositions exist.
