Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723726, here are decompositions:

19 + 8723707 = 8723726
73 + 8723653 = 8723726
157 + 8723569 = 8723726
229 + 8723497 = 8723726
307 + 8723419 = 8723726
367 + 8723359 = 8723726
373 + 8723353 = 8723726
379 + 8723347 = 8723726

Showing the first eight; more decompositions exist.
