Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623844, here are decompositions:

13 + 8623831 = 8623844
37 + 8623807 = 8623844
43 + 8623801 = 8623844
127 + 8623717 = 8623844
157 + 8623687 = 8623844
193 + 8623651 = 8623844
223 + 8623621 = 8623844
241 + 8623603 = 8623844

Showing the first eight; more decompositions exist.
