Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745938, here are decompositions:

109 + 8745829 = 8745938
139 + 8745799 = 8745938
241 + 8745697 = 8745938
367 + 8745571 = 8745938
571 + 8745367 = 8745938
631 + 8745307 = 8745938
739 + 8745199 = 8745938
769 + 8745169 = 8745938

Showing the first eight; more decompositions exist.
