Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723508, here are decompositions:

11 + 8723497 = 8723508
29 + 8723479 = 8723508
67 + 8723441 = 8723508
71 + 8723437 = 8723508
89 + 8723419 = 8723508
109 + 8723399 = 8723508
149 + 8723359 = 8723508
191 + 8723317 = 8723508

Showing the first eight; more decompositions exist.
