Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723706, here are decompositions:

29 + 8723677 = 8723706
53 + 8723653 = 8723706
67 + 8723639 = 8723706
97 + 8723609 = 8723706
113 + 8723593 = 8723706
137 + 8723569 = 8723706
223 + 8723483 = 8723706
227 + 8723479 = 8723706

Showing the first eight; more decompositions exist.
