Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723384, here are decompositions:

31 + 8723353 = 8723384
37 + 8723347 = 8723384
67 + 8723317 = 8723384
73 + 8723311 = 8723384
181 + 8723203 = 8723384
193 + 8723191 = 8723384
277 + 8723107 = 8723384
331 + 8723053 = 8723384

Showing the first eight; more decompositions exist.
