Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723942, here are decompositions:

13 + 8723929 = 8723942
43 + 8723899 = 8723942
109 + 8723833 = 8723942
211 + 8723731 = 8723942
349 + 8723593 = 8723942
373 + 8723569 = 8723942
421 + 8723521 = 8723942
463 + 8723479 = 8723942

Showing the first eight; more decompositions exist.
