Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723546, here are decompositions:

67 + 8723479 = 8723546
109 + 8723437 = 8723546
127 + 8723419 = 8723546
193 + 8723353 = 8723546
199 + 8723347 = 8723546
229 + 8723317 = 8723546
397 + 8723149 = 8723546
409 + 8723137 = 8723546

Showing the first eight; more decompositions exist.
