Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723526, here are decompositions:

5 + 8723521 = 8723526
29 + 8723497 = 8723526
43 + 8723483 = 8723526
47 + 8723479 = 8723526
67 + 8723459 = 8723526
89 + 8723437 = 8723526
103 + 8723423 = 8723526
107 + 8723419 = 8723526

Showing the first eight; more decompositions exist.
