Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723700, here are decompositions:

23 + 8723677 = 8723700
47 + 8723653 = 8723700
61 + 8723639 = 8723700
107 + 8723593 = 8723700
131 + 8723569 = 8723700
149 + 8723551 = 8723700
179 + 8723521 = 8723700
241 + 8723459 = 8723700

Showing the first eight; more decompositions exist.
