Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723668, here are decompositions:

29 + 8723639 = 8723668
59 + 8723609 = 8723668
137 + 8723531 = 8723668
227 + 8723441 = 8723668
269 + 8723399 = 8723668
281 + 8723387 = 8723668
347 + 8723321 = 8723668
587 + 8723081 = 8723668

Showing the first eight; more decompositions exist.
