Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623874, here are decompositions:

31 + 8623843 = 8623874
43 + 8623831 = 8623874
67 + 8623807 = 8623874
73 + 8623801 = 8623874
157 + 8623717 = 8623874
223 + 8623651 = 8623874
271 + 8623603 = 8623874
613 + 8623261 = 8623874

Showing the first eight; more decompositions exist.
