Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623880, here are decompositions:

37 + 8623843 = 8623880
73 + 8623807 = 8623880
79 + 8623801 = 8623880
151 + 8623729 = 8623880
163 + 8623717 = 8623880
193 + 8623687 = 8623880
229 + 8623651 = 8623880
241 + 8623639 = 8623880

Showing the first eight; more decompositions exist.
