Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623040, here are decompositions:

3 + 8623037 = 8623040
7 + 8623033 = 8623040
37 + 8623003 = 8623040
67 + 8622973 = 8623040
157 + 8622883 = 8623040
163 + 8622877 = 8623040
193 + 8622847 = 8623040
199 + 8622841 = 8623040

Showing the first eight; more decompositions exist.
