Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723894, here are decompositions:

7 + 8723887 = 8723894
43 + 8723851 = 8723894
61 + 8723833 = 8723894
73 + 8723821 = 8723894
163 + 8723731 = 8723894
241 + 8723653 = 8723894
373 + 8723521 = 8723894
397 + 8723497 = 8723894

Showing the first eight; more decompositions exist.
