Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723834, here are decompositions:

13 + 8723821 = 8723834
103 + 8723731 = 8723834
127 + 8723707 = 8723834
157 + 8723677 = 8723834
181 + 8723653 = 8723834
241 + 8723593 = 8723834
283 + 8723551 = 8723834
313 + 8723521 = 8723834

Showing the first eight; more decompositions exist.
