Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723670, here are decompositions:

17 + 8723653 = 8723670
31 + 8723639 = 8723670
61 + 8723609 = 8723670
101 + 8723569 = 8723670
139 + 8723531 = 8723670
149 + 8723521 = 8723670
173 + 8723497 = 8723670
191 + 8723479 = 8723670

Showing the first eight; more decompositions exist.
