Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723498, here are decompositions:

19 + 8723479 = 8723498
61 + 8723437 = 8723498
79 + 8723419 = 8723498
139 + 8723359 = 8723498
151 + 8723347 = 8723498
181 + 8723317 = 8723498
307 + 8723191 = 8723498
349 + 8723149 = 8723498

Showing the first eight; more decompositions exist.
