Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723432, here are decompositions:

13 + 8723419 = 8723432
73 + 8723359 = 8723432
79 + 8723353 = 8723432
229 + 8723203 = 8723432
241 + 8723191 = 8723432
283 + 8723149 = 8723432
379 + 8723053 = 8723432
433 + 8722999 = 8723432

Showing the first eight; more decompositions exist.
