Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723532, here are decompositions:

11 + 8723521 = 8723532
53 + 8723479 = 8723532
73 + 8723459 = 8723532
109 + 8723423 = 8723532
113 + 8723419 = 8723532
173 + 8723359 = 8723532
179 + 8723353 = 8723532
211 + 8723321 = 8723532

Showing the first eight; more decompositions exist.
