Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693720, here are decompositions:

31 + 8693689 = 8693720
43 + 8693677 = 8693720
67 + 8693653 = 8693720
97 + 8693623 = 8693720
103 + 8693617 = 8693720
199 + 8693521 = 8693720
229 + 8693491 = 8693720
313 + 8693407 = 8693720

Showing the first eight; more decompositions exist.
