Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723558, here are decompositions:

7 + 8723551 = 8723558
37 + 8723521 = 8723558
61 + 8723497 = 8723558
79 + 8723479 = 8723558
139 + 8723419 = 8723558
199 + 8723359 = 8723558
211 + 8723347 = 8723558
241 + 8723317 = 8723558

Showing the first eight; more decompositions exist.
