Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623940, here are decompositions:

37 + 8623903 = 8623940
43 + 8623897 = 8623940
97 + 8623843 = 8623940
109 + 8623831 = 8623940
139 + 8623801 = 8623940
211 + 8623729 = 8623940
223 + 8623717 = 8623940
337 + 8623603 = 8623940

Showing the first eight; more decompositions exist.
