Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723732, here are decompositions:

79 + 8723653 = 8723732
139 + 8723593 = 8723732
163 + 8723569 = 8723732
181 + 8723551 = 8723732
211 + 8723521 = 8723732
313 + 8723419 = 8723732
373 + 8723359 = 8723732
379 + 8723353 = 8723732

Showing the first eight; more decompositions exist.
